just so everyone is aware. I followed this video along, used the 90° weld on Bungs so the ecu doesn't trigger check engine light. worked like a charm and the car is so much more fun to drive. the only thing I recommend Andre the Victor reinz gaskets for the headers. I've had them checked for leaks and they've held up great 30k miles so far.
Lol I like you man. Great video. People always bash eBay stuff because it doesn't cost $1633642864 dollars like most bmw performance parts.. But pipes are pipes Lol metal is metal. Regardless of where it came from. I appreciate videos like this
DLJW Productions Ebay headers a HUGE in the E46 community, I have a set myself and know several others. You just don't want to skimp on major things like harness' or stuff like that.
great vid, but someone explain to me one thing...when car runs closed loop, it means ECU reads preCat O2 sensors and adjusts fuel trims accordingly, now when position of O2 sensors are far away from exhaust ports (also from factory placement) and plus you did some extenders O2 readings will be totally messed up, so how much will this affect Fuel Trims?? could not ECU react on incorrect reading due to Closed loop situation and mess up Air/Fuel mixture? u will run ether Rich or Lean...No? someone give me answer on this if u have more information, thanks.
Sorry for the late response, here’s my explanation: The ECU only uses the pre cat O2 sensors to adjust fuel and air mixture, not the post cat. The extenders used in the videos were used ONLY on the post cat sensors, which does not affect the ECU’s readings. The position of the sensors doesn’t matter for readings, but having extenders will affect it, which is why you only use them on post cat sensors. Fuel/Air mix can still get slightly messed up with new headers so it’s a good idea to get a stage one tune.
Hell yeah your video helped a lot I showed a couple of my e46 buddy's and we are going to give it a try and yes post the link of the forum and I will go check it out thank you again!
Thanks for your DIY, it helps me to do it for my E46 325CI. But for me, the 90° extender can't pass with the heat shield for the nearest header. I should have cut the riser as you. Instead, I've remove the secondary O2 sensor and screw a cap. The secondary O2 sensor is plugged but is just maintained in the engine bay. No CELL at all. Important : buy OEM's gasket instead of those supplied (for top and bottom) otherwise guaranteed leaks.
Great video. Glad to see there are some great deals to be had on eBay. I'll be installing some headers on my e90 330i, and hope that I'm as successful as you at installing them. Cheers!
So for the welding of the o2 sensor bung, why couldn't you use a threaded one and thread into the existing bung on the header? 90 Degree Angled O2 Check Engine Light CEL Fix Oxygen Spacer Exhaust Extension www.amazon.com/dp/B00B1U6I54/ref=cm_sw_r_cp_awd_XL5hxbH4T0QT7 For a example of one. I'm wondering because I'm planning on doing this soon.
+Jeffrey Kersten Did he ever say where he lives? You might be out of luck living there since they check for smog. Where I live you pull into the inspection booth, hit your horn, flash your lights, hit the brakes, and he pulls any drum brakes to check the pads (on one wheel). That is it. So here you can pretty much do what ever you want as long as it isn't loud enough to get their attention. OH but you can't have earplugs hanging from the rear mirror that is a fail.
+deebo gotyou You look as dum as you sound. Anyone who has a pic of Deebo as there head shot must be a dipshiit hiding on his computer wishing he could afford the maintenance on bmw e46 m3 , but could only dream of owning one. Mind your business and give me my bike back
A question mate. I would like to do the same but...isn't too loud, I mean, I will use my 323ci daily and my Girlfriend hates that "tuning" super loud exhaust sounds? WHat do you say?
Mate, can you provide a little drawing or something with measurements so that I can replicate your results? Thank you a props for the job well done, as Edd China would say! Also, there are some high flow cats that you may be interested in looking at.
Just saw it right now didn't realize your ig was linked, thanks so much! So those pre threaded bung holes on the front / rear of the eBay headers, you only used the front and didn't use the rear side correct? The pre threaded spot that was already there? Or did you actually drill/weld a new hole as far back as you could? Also did you have enough room with the o2 sensor length or did you have to buy a longer extended o2 sensor? Thanks !
e46orozco I used the holes they put on there. I just cut off the bung for one of them. Yes I had enough room for stock length O2s but I did have to zip tie the wire of one of the O2 sensors so that it would not be resting on the header.
Thanks for providing the link for the cel fix! i plugged my rear 02's and regret it. If you find yourself making another video include exterior sound pleasee lol &If i can add, it helps getting gaskets without head shields for install
I had these headers put in years ago and left the 02 sensors out. Are the 02 sensor at a spot where you could still change one out if it failed without pulling the whole header out? I just bought the extenders after watching this video and I want to stick my 02's in to get rid of the annoying engine light.
+Marq333 Sorry to hear that. I have heard that the rear o2 on the m3 is used for fuel trim so I would recommend eliminating the light with a tune and leaving the o2 directly in the exhaust stream.
Hey I already got headers onto my 330i and was wondering if there was a way to put the 90 degree pieces on the regular o2 bung to extend it long enough with another part so I dont have to drill and weld and not have the check engine light? Your car sounds just like mine haha but good vid
Alan Lucas If there is enough clearance you can just screw the 90 degree elbow in. My bungs were running into my heat shield so it required me to cut and weld.
They seem to work fine. I had the meyle hd before and got a lot of front end vibration after only 1 track event. Powerflex has been fine for me and has held up on the race track.
I know this is a little old but you appear to have the exact same headers i bought for my 330Ci. Did you have an issue with the pre-cat o2 sensors? I had to use a 90 degree adapter and im wondering if that pulled the sensor out of the flow enough to cause the car to bog occasionally due to lack of sensing and adjustments in AFR. Also, did yours not quite reach the stock exhaust flanges?
I'm currently do this to my e46 330ci( my daily) is it possible to get the angle of the o2 extenders that way I can make the install as quick as possible? Also did you leave your secondary air pump on
So if I buy these headers and take it to a shop you think they would know about doing the O2 extender set up you did to avoid Check Engine light? Too afraid to do it myself since I'm new to the BMW world, just got my first 330i two months ago.
+TwistedCrooks Oh for some reason I thought you were asking about inspections. I'm not sure if a shop would do it because I am pretty sure tampeing with the O2 sensors are illegal. It can't hurt to ask them though. You can also get a tuning chip which will remove the CEL light.
Awesome video! How many of those 90 degree things did you use? Was it one on each header? Or just the rear header? How long did it take you I wish you could show how you did it step by step...
2 of the 90 degree pieces. One on each header. I am going to post a pic on the E46 forum to show what it looks like installed. It took me a good six hours of tinkering because I had to figure out how to get the damn things to fit. If I did it on someone else's car it would be very quick now. Probably 3-4 hours taking my time. I didn't think people would watch this. I will make more detailed videos when I build the race exhaust, gut the car, and cage the car :)
my headers are stainless steel and i was told by a shop the angled o2 sensor needs to be tig welded? was this the same situation with you or did you just arc weld?
+weirdchildlikescake I just mig welded it. Yes they are correct, tig welding is the "doing it right" method. Mig welding is more of a "it's an exhaust and I don't really care" method.
I been doing some research, the only difference is the 323i are slightly shorter the the rest of the 3series. But you can still run any 3 series ebay header aslong as you use that series exhaust system. Good vid man, nice info, you now have enough street credit for protection in a state prison shower-room.
I see you had trouble going into 1st gear. I have this issue too where i have to push it very hard for the gear to go in. What can be the cause for this? 03 330i zhp 6 speed, if that matters.
Giovanny Zepeda De La Rosa It might be your pilot bearing. Dependimg on your mileage it could be your transmission fliud, but unless its leaking or someone tampered with the level of the fluid thats probably not it. A good way to tell if it is your pilot bearing is bad is when you are going into first gear, there is ocasionally a clunking sound.
MiniMe Hey I used an acetylene torch and heated it until the nuts turned red then removed! Some of the studs snapped off. I cut relief cuts in the sides of the flange and pressed out the old studs. I replaced them with nuts/bolts
ZentRose Finnaly got the new headers on. the one flange is about 1 inch away from the exhaust pipe. do you think i could bolt it and it would seal or will a shop have to weld an extension on?
E39s are nice! and thanks for the comment I didn't mean to sound negative about it. I liked quiet and smooth for daily driving, but the time has come to strip it down for track work.
Hey whats up bro. I have a 2003 e46 m3 vert with smg with 19's. I have the titanium megan racing exhaust and an ar20 resonator as of now. Bought the car 3 1/2 years ago with 83k and has now about 97k. Do you think I have to many miles to add headers? I must admit, my car pulls nice and the only repairs I've done are fuel pump, alternator and salmon relay. I've heard bad shiit on the forums about ebay headers. They don't line up, they don't last, and my favorite...If you can't afford a real set of headers...supersprint , Dinan etc.. then you shouldn't own an M3. Are they worth it? Hard to install? I can't weld but I'm very handy, did the alternator and fuel pump myself. Or should I buy the Agency Power headers for$1,000. What do you think? Also, do you think a more expensive set of headers will sound better than the ebay one's? Thanks in advance for your imput
i have a m3. dont buy to cheap for m engines. i spent over a k on my coilovers and more on my wheels. i plan to spend 1-2k for headers but i have 101k on so i might just wait
Hey is there any chance that you could take a picture of your non fouler modification that you did in more depth? Like a pic so i can cut and weld it myself and have my mechanic then put it on for me, id appreciate it. Cause bought the same exact headers and the same exact CEL fix, (the two 90 degree elbow extension mod.) And I just want to make sure exactly where to cut and weld the extension on that way I can just have it all ready to go for my mechanic to put it straight on my car. I would seriously thank you so much I'm on e46 fanatics and everywhere I go people don't provide photos of that type of Cel type mod. Everyone uses the basic spark plug fouler mod which doesn't really work because it doesn't bend away from the exhaust fumes like the 90 degree one does. Thanks!
+ZentRose Thanks for the input! Not particularly worried about that but everyone says its the best mod you can get, yet so few have. They're going on after I save up enough for subframe bushings, motor mounts and a sway bar
Hey great video, i'm thinking of putting these on my e83 x3 (I know, who would do that to an x3?) Anyways I was just curious what year of e46 you have, our cars are built on the same chassis and we both share the same engine/transmission. Only reason I ask about the year is because some people on the forums claim that moving the o2 sensors away from the flow of exhaust will still trigger a cel. Thanks in advance for the reply!
onslot72 This is a 2001 330ci. I've been daily driving it with no check engine light. Also the emissions obd2 test is clear. Can you share which years are having the problem? Thank you.
+Will S I don't have to worry about rust where I live but that is probably a good point. I will pull them and inspect them when smog comes around in a couple years.
+ZentRose oh okay that's good. Does your car smell with the cats off? I'm thinking of getting headers because I'm running an supersprint and eisenmann setup and it will sound amazing, but I'm worried about the smell. I believe older cars tend to smell without cats. My friends frs doesn't smell without cats, but his car is new.
One day I was up at work with my dad at classic bmw and a manager that should not be a Manager asked why there were Cadillac converters on a bmw Just thought I should tell someone
When i installed headers on my e 46 2001 325ci ,after installation i had no cel light and i dont think you get a cel light for putting headers , but what you get is (Service Engine Soon Light) once you give it a rev it pops out and ive read that it means that there is no cats and 02 sensor's can see that you got headers , so my car still runs fine with the headers but sometimes after a long drive if you let it idle, you can feel how engine misfiring, i think i got too much fuel going in which causes it to do so, and a smell after installed headers dDAMN you can die breathing that sht while you are idling standing still, but the car has definitely gained a lots of power especially on low and high ends , and mid range it sucks like 1500-2700 rpm engine misfiring idk what is going on and it has no pull for shtm but after 3k its like a rocket , and idk what to do so i think im gonna install after market cats in.
This is exactly what happen to me. I took the headers off and the misfiring got worse. I changed the ccv and problem solved! The thing is you need to get a tune when you have headers or you will have issues with fuel injectors and other stuff if you run them long enough. So that also could be your problem. All headers give problems if ran without a tune for a certain amount of time.
just so everyone is aware. I followed this video along, used the 90° weld on Bungs so the ecu doesn't trigger check engine light. worked like a charm and the car is so much more fun to drive. the only thing I recommend Andre the Victor reinz gaskets for the headers.

as long as u love you car and have the pride and passion to work on it. screw what others think. your the one enjoying it. great review
Lol I like you man. Great video. People always bash eBay stuff because it doesn't cost $1633642864 dollars like most bmw performance parts.. But pipes are pipes Lol metal is metal. Regardless of where it came from. I appreciate videos like this

How did exhaust hold up ?
had these on my e36 for yrs. fitment was fine. holding up just fine too
great vid, but someone explain to me one thing...when car runs closed loop, it means ECU reads preCat O2 sensors and adjusts fuel trims accordingly, now when position of O2 sensors are far away from exhaust ports (also from factory placement) and plus you did some extenders O2 readings will be totally messed up, so how much will this affect Fuel Trims?? could not ECU react on incorrect reading due to Closed loop situation and mess up Air/Fuel mixture? u will run ether Rich or Lean...No? someone give me answer on this if u have more information, thanks.

ZentRose your good
Thanks for your DIY, it helps me to do it for my E46 325CI. But for me, the 90° extender can't pass with the heat shield for the nearest header. I should have cut the riser as you.

Important : buy OEM's gasket instead of those supplied (for top and bottom) otherwise guaranteed leaks.
+Damien Peignaux Leaving an O2 Sensor out doesn't cause a Check Engine to Light up?
I'm surprised too, but I didn't have any check engine light. So I don't want to try to unplug it.
so how many o2 sensors did you plug in?
The 2 primary and only 1 secondary (the other secondary is replaced by a cap)
Are you in EU or US?
I got that same sounds from my exhaust for free. With 1 mod. Clogged cats. That forced me to remove my o2 sensors for awhile so I could drive muahaha
Great video. Glad to see there are some great deals to be had on eBay. I'll be installing some headers on my e90 330i, and hope that I'm as successful as you at installing them. Cheers!
Uncle Ben Nice! The E90 330i is a fun car and already much faster than my 330 haha
So for the welding of the o2 sensor bung, why couldn't you use a threaded one and thread into the existing bung on the header?
90 Degree Angled O2 Check Engine Light CEL Fix Oxygen Spacer Exhaust Extension www.amazon.com/dp/B00B1U6I54/ref=cm_sw_r_cp_awd_XL5hxbH4T0QT7
For a example of one.
I'm wondering because I'm planning on doing this soon.
did u ever end of using that piece??
hey, nice video. could you link me where you got those o2 angle extenders? :)
How did you pass smog? Im in sac area in california and want these, just worried about smog
+Jeffrey Kersten Did he ever say where he lives? You might be out of luck living there since they check for smog. Where I live you pull into the inspection booth, hit your horn, flash your lights, hit the brakes, and he pulls any drum brakes to check the pads (on one wheel). That is it.

Can you provide links for parts please?
did u pass smog with them on?
Send me the link to get the parts you used please brother
A question mate. I would like to do the same but...isn't too loud, I mean, I will use my 323ci daily and my Girlfriend hates that "tuning" super loud exhaust sounds?
WHat do you say?
Soro GuÊ change girlfriend
You ought to buy more headers, weld the extenders on, and sell em to chumps like me without a welder! I can smell the profit from here.
+Greg Steele That is probably a good idea but I moved to an apartment now and don't have a safe location to weld.
Mate, can you provide a little drawing or something with measurements so that I can replicate your results?
Thank you a props for the job well done, as Edd China would say!
Also, there are some high flow cats that you may be interested in looking at.
Just saw it right now didn't realize your ig was linked, thanks so much!
So those pre threaded bung holes on the front / rear of the eBay headers, you only used the front and didn't use the rear side correct? The pre threaded spot that was already there? Or did you actually drill/weld a new hole as far back as you could? Also did you have enough room with the o2 sensor length or did you have to buy a longer extended o2 sensor? Thanks !
e46orozco I used the holes they put on there. I just cut off the bung for one of them. Yes I had enough room for stock length O2s but I did have to zip tie the wire of one of the O2 sensors so that it would not be resting on the header.
Thanks for providing the link for the cel fix! i plugged my rear 02's and regret it.
If you find yourself making another video include exterior sound pleasee lol
&If i can add, it helps getting gaskets without head shields for install
ok sounds good. I will get exterior sound soon. thanks
I've been looking all over eBay for these headers and the best I could find is 250 you know a link I can get them cheaper? You mentioned 100$
I had these headers put in years ago and left the 02 sensors out. Are the 02 sensor at a spot where you could still change one out if it failed without pulling the whole header out? I just bought the extenders after watching this video and I want to stick my 02's in to get rid of the annoying engine light.
3:51 is that an s2000
The o2 extenders didn't work for my E46 M3 :/
+Marq333 Sorry to hear that. I have heard that the rear o2 on the m3 is used for fuel trim so I would recommend eliminating the light with a tune and leaving the o2 directly in the exhaust stream.
So you only needed to modify the post cat o2 sensors to make them fit?
Great video! Question though..your exhaust otherwise stock?
Josh River Yes Stock exhaust.
Josh River
I haven’t seen a e92 diy headers for a 328i or 335i :(
Hello! Thanks for the video! Is the engine checklight on after installing this headers?
Hey I already got headers onto my 330i and was wondering if there was a way to put the 90 degree pieces on the regular o2 bung to extend it long enough with another part so I dont have to drill and weld and not have the check engine light? Your car sounds just like mine haha but good vid
Alan Lucas If there is enough clearance you can just screw the 90 degree elbow in. My bungs were running into my heat shield so it required me to cut and weld.
ZentRose Aye man I bought some ebay headers for my e46 330i and the o2 sensors hit the heat shield do I have to cut them and weld the oem ones to it .
Great video I subscribed what o2 sensor extenders did you use?
So do you also put the other o2 sensors on the other header?
Do you remember which headers they were?
hey, do you have a link to the headers? the ones I see done have the place at the ends to bolt up the exhaust
Could you tell me what was the modification you had to do to make these headers fit? What exactly do I need to get? Other than the O2
how do you get past inspection?
+Romell Blanks this
Romell Blanks keep your old headers. Change them out for a day
where do you get the o2 extenders
Angel Villanueva you can get them on eBay or auto zone
How is the exhaust smell with out the cats now? Annoying or not a problem? Thanks for the video gives me motivation to do headers now
I like the smell of no cats so it's not annoying to me. Anyway, the only one who has to deal with the smell is the driver who tailgates me :)
ZentRose Haha. Noticed you have power flex fcabs...how do you like them? Good luck with everything and keeping making e46 vids!
They seem to work fine. I had the meyle hd before and got a lot of front end vibration after only 1 track event. Powerflex has been fine for me and has held up on the race track.
I know this is a little old but you appear to have the exact same headers i bought for my 330Ci. Did you have an issue with the pre-cat o2 sensors?

I have a 323ci e46. That header would work?
Can you tell me which eBay seller you bought these from? Thanks!
so you didnt get a check engine light?? sweet
So if I buy these headers and take it to a shop you think they would know about doing the O2 extender set up you did to avoid Check Engine light? Too afraid to do it myself since I'm new to the BMW world, just got my first 330i two months ago.
+TwistedCrooks It depends if your state does visual checks. This would not pass visual inspection but not all places require visual inspection.
+Nick Donato I just had my car inspected like 4 days ago and no they don't do visual inspections. I'm in oregon
+TwistedCrooks Oh for some reason I thought you were asking about inspections. I'm not sure if a shop would do it because I am pretty sure tampeing with the O2 sensors are illegal. It can't hurt to ask them though. You can also get a tuning chip which will remove the CEL light.
Awesome video! How many of those 90 degree things did you use? Was it one on each header? Or just the rear header? How long did it take you I wish you could show how you did it step by step...
2 of the 90 degree pieces. One on each header. I am going to post a pic on the E46 forum to show what it looks like installed.
It took me a good six hours of tinkering because I had to figure out how to get the damn things to fit. If I did it on someone else's car it would be very quick now. Probably 3-4 hours taking my time.
I didn't think people would watch this. I will make more detailed videos when I build the race exhaust, gut the car, and cage the car :)
can this be dont without removing the engine mount?
Link to these headers online?
Are the headers a pain to install? An about how long did the install take?
Kyle Noll I would not want to do it again. It took me 6 hours due to test fitting. It's worth it though 🚗💨 😎
hey man think you could send me the link to these ? Thanks !
my headers are stainless steel and i was told by a shop the angled o2 sensor needs to be tig welded? was this the same situation with you or did you just arc weld?

+ZentRose that's what I was thinking, they told me they'd f it up if they did it that way. how was your weld?
+weirdchildlikescake My weld was pretty terrible. It holds up on the track though with lots of high rpm driving.
Sounds good! Lucky for me i own a welder too! do you remember what units you bought?
Fabian G. I just got them off ebay. I bought the cheapest ones.
I been doing some research, the only difference is the 323i are slightly shorter the the rest of the 3series. But you can still run any 3 series ebay header aslong as you use that series exhaust system. Good vid man, nice info, you now have enough street credit for protection in a state prison shower-room.
awesome stuff! love your videos!
Thanks!
rubbery?
I see you had trouble going into 1st gear. I have this issue too where i have to push it very hard for the gear to go in. What can be the cause for this? 03 330i zhp 6 speed, if that matters.

in witch state are you located?
how have they held up in the long run? any side effects? any idea how much horsepower gain youve gotten?
+Chris S They are great, no side effects. I didn't dyno it so no idea of horsepower.
sweet. i was looking into getting a set. any idea what seller/brand you bought from?
How the hell did you get the exhaust flanges separated? I cant get a socket onto the top two nuts due to rust. Any recommendations?
MiniMe Hey I used an acetylene torch and heated it until the nuts turned red then removed! Some of the studs snapped off. I cut relief cuts in the sides of the flange and pressed out the old studs. I replaced them with nuts/bolts

E39s are nice! and thanks for the comment
I didn't mean to sound negative about it. I liked quiet and smooth for daily driving, but the time has come to strip it down for track work.
The headers in your link are 500 dollars are they the right ones?
jedidiah james They should be $100. Apparently they raised prices when demand went up. The price will go back down.
Do the headers come out from the bottom of the car or the top?
MiniMe bottom
I can't seem to find the correct headers for my 2001 325, where did you get yours?
Saarim Siddiqui I just ordered them off ebay and made sure the seller listed my vehicle as a fit.
ZentRose I've been looking around for awhile for one that can fit 330/325 but I still can't find one. Can you link me?

Also, do you think a more expensive set of headers will sound better than the ebay one's? Thanks in advance for your imput
i have a m3. dont buy to cheap for m engines. i spent over a k on my coilovers and more on my wheels. i plan to spend 1-2k for headers but i have 101k on so i might just wait
I have a zhp 330i. want to make it really loud any tips? and also do you do anythying to pass california emission laws??
Dunken135 you wanna make it loud? drill a hole inn your exhaust .
Hey is there any chance that you could take a picture of your non fouler modification that you did in more depth? Like a pic so i can cut and weld it myself and have my mechanic then put it on for me, id appreciate it.
Cause bought the same exact headers and the same exact CEL fix, (the two 90 degree elbow extension mod.)
And I just want to make sure exactly where to cut and weld the extension on that way I can just have it all ready to go for my mechanic to put it straight on my car. I would seriously thank you so much I'm on e46 fanatics and everywhere I go people don't provide photos of that type of Cel type mod. Everyone uses the basic spark plug fouler mod which doesn't really work because it doesn't bend away from the exhaust fumes like the 90 degree one does. Thanks!
e46orozco Yeah I can. I will get back to you. Thanks
ZentRose I would seriously thank you so much I would even pay you if you'd like, I can pay you via the Google wallet app :D
e46orozco Hey I put up a picture on instagram. It was hard to take a good picture though. Can you let me know if it helps?
ZentRose I figured it would be hard, what's your instagram name I'll check it out, I appreciate it brotha.
Hey which header exactly u got from ebay... brand???? Thanks
That s2000 at 3:51 sexy as fuck!
great video, i´m from germany didn´t understand everything haha so did you feel an increase of power?
Chris FLPS Yes it was a noticeable increase. Enjoy your car!
Update? How did they hold up so far?
+Gidenkidenk They held with no leaks so far. They are a great bargain but the biggest challenge is the install.
+ZentRose Thanks for the input! Not particularly worried about that but everyone says its the best mod you can get, yet so few have. They're going on after I save up enough for subframe bushings, motor mounts and a sway bar
Hey great video, i'm thinking of putting these on my e83 x3 (I know, who would do that to an x3?) Anyways I was just curious what year of e46 you have, our cars are built on the same chassis and we both share the same engine/transmission. Only reason I ask about the year is because some people on the forums claim that moving the o2 sensors away from the flow of exhaust will still trigger a cel. Thanks in advance for the reply!
onslot72 This is a 2001 330ci. I've been daily driving it with no check engine light. Also the emissions obd2 test is clear.
Can you share which years are having the problem? Thank you.
very nice welds
Where do you live dude? If you could I'd like some help installing my headers :) Im in LA
Why didn't you coat the headers? Not worried about rust? I'm interested
+Will S I don't have to worry about rust where I live but that is probably a good point. I will pull them and inspect them when smog comes around in a couple years.
+ZentRose can you make a video where we can hear the header sound better?
+ZentRose oh okay that's good. Does your car smell with the cats off? I'm thinking of getting headers because I'm running an supersprint and eisenmann setup and it will sound amazing, but I'm worried about the smell. I believe older cars tend to smell without cats. My friends frs doesn't smell without cats, but his car is new.
Will S why would it smell?
just Faisal because the cats is what restricts the emissions the car puts out.
One day I was up at work with my dad at classic bmw and a manager that should not be a Manager asked why there were Cadillac converters on a bmw
Just thought I should tell someone
I can't install the headers myself...I am very sad. I would get them but if I took them somewhere it would be like 333.33 for installation :^(
When i installed headers on my e 46 2001 325ci ,after installation i had no cel light and i dont think you get a cel light for putting headers , but what you get is (Service Engine Soon Light) once you give it a rev it pops out and ive read that it means that there is no cats and 02 sensor's can see that you got headers , so my car still runs fine with the headers but sometimes after a long drive if you let it idle, you can feel how engine misfiring, i think i got too much fuel going in which causes it to do so, and a smell after installed headers dDAMN you can die breathing that sht while you are idling standing still, but the car has definitely gained a lots of power especially on low and high ends , and mid range it sucks like 1500-2700 rpm engine misfiring idk what is going on and it has no pull for shtm but after 3k its like a rocket , and idk what to do so i think im gonna install after market cats in.
damn I've never heard of the car running poorly after header install
it runs smooth after 3k rpm
before that feels like its misfiring and also exhaust backfiring too
+Andrey Arkashin could you make a video? and does it just sound like misfire or does it actually misfire and sends a misfire code?
it doesnt send the code and feels like a misfire ill make a video later and post it over here.
This is exactly what happen to me. I took the headers off and the misfiring got worse. I changed the ccv and problem solved! The thing is you need to get a tune when you have headers or you will have issues with fuel injectors and other stuff if you run them long enough. So that also could be your problem. All headers give problems if ran without a tune for a certain amount of time.
do they make these for e36
e36 has a great header from factory, lots of people put e36 header on e46, but that needs some modification
will this work on smg 330ci
yes
that's the 5 in irvine isn't it? lol
+Marc Daneo yes sir
+ZentRose I wish you still lived in Irvine or SoCal. You're the type of enthusiast I get along with haha
+samchoochiu I just moved back to Orange for work.
ZentRose My gosh :D Hope I see you at an auto event sometime. Are you going to bimmerfest?
Lol u stay right by me how much would you charge to install?
+yars fbi I don't work on customer cars anymore.
Aww bummer ):
where did you purchase the o2 extenders? how are the headers holding now?
So your not running cats
Sean Bradley negative. BMW e46s have cats in the headers ONLY their are 2 resonators throughout the system
Hey man good video and tips but quick question.. will those headers fit a 323i 2.5 bmw?? Please let me know thanks
Nope it wont you need to get the right one for 323/328 2.5L. I learned the hard way but disnt lose any money just time.
I cant wait!
can someone help me find one on ebay i have a 2005 bmw 325ci
Pauli Chinatti helloo ?!?!
+preet singh shit I do lol, I bought some and sold them due to not having time to get to them. Now I can't find any headers on ebay for under $500
Saw that s2k at 3:52 lmao 👍😎
haha yep I had to put that clip in the video!
How the heck do you add emojis to a youtube video comment? That is pretty neat.
Lol he said it so boring😂😂😂
