Yea but that's for a brand new genuine bmw cat. Trying to sell a used cat for maybe $500-600 and at that point you can purchase a new aftermarket catalytic converter for that price. So it's probably worth $200-300. I sold all the cat material for $145!
Lol bro I legit have a guy wanting to sell me a cat he gutted himself for $100. What the fuck is a cat worth. Who wants a stock oem cat for $1000? Some old man? You’ll have it up for sale for like a year before you even get an offer! Lol
I have been working on my exhaust lately and was told that I can empty my stock catalytic converter and will serve the same purpose as a downpipe.. It really didnt make any sense at first but then dug more into it and it seems pretty legit.. What differentiates a 500$ ER downpipe from an emptied Catalytic Converter? i just buy a 150 us chaep cat on ebay
Did you get any dash or engine light after the whole process did you do this with a tune or just simply cleared out the cat and bolted everything back on. Am asking because am thinking of doing this but don’t want any engine light on???
Absolutely nothing wrong with doing this. A downpipe is literally just a pipe. People can be such tightwads. You saved yourself the hassle of unbolting the stock piece and saved yourself some cash for more mods. If you want to revert to stock, I'm sure there are hundreds of OEM downpipes out there. These ppl in the comments are just pissed they didn't think about it first.
I do agree with you but at the same time, I sold my oem catted downpipes to a recycler for $315 each and paid $450 for both catless downpipes from vrsf. So I made $180 on it. But my cats aren't as easy to get to to do it this way on my 650i xdrive
It works but the cated pipes (if they aren't clogged) are worth more than a decent set of catless ones. Kind of tricky to get at them in a time effective manor though.
Where do you get the nice shifters? I have the e60 with sport paddles sounds amazing how much would you charge for the gutting of rhe downpipe and does it still pass o2 sensor or check engine light? I want my resonator deleted and whatever else that can be done
No need to pay, he showed you how to do it super easy by yourself. I wouldn't recommend it since that cat your gutting is super expensive and depending on what state you live in you won't pass smog. At least if you save your oem cat you can swap out the cat less downpipe and pass smog then put the cat less back in. Edit: it will cause a check engine light that can be fixed with a tune.
Guys 😂! DON’T DO THIS! Just buy a catless down pipe from eBay for 100-200$ and keep your catted down pipe for later in case you need it. Or just sell your good catted down pipe for 500$ or more to some idiot that ruined there’s doing this. This is a 1000$+ part to replace if you require it later on.
This is worth it on a Xi. Especially because if you get vrsf or any name brand you have to literally hammer it almost shut to make it fit. Not worth buying something new just to bend it and hammer it into place.. and that 3” inch becomes more like a 2”
Marcowy yes this definitely works, it becomes a “catless downpipe”...I never realized it would be this easy though honestly. Only downside is you can’t go back to stock if necessary for emissions without buying another OEM downpipe but that doesn’t matter in every state/situation.
Please help i gutted my cats today and for some reason when i put everything back together it sounds almost as if my car sound is exiting from the downpipe instead of the rear exhaust tips
@@Fastest__M i dont see how tjat could have happened honestly yhe sound is comimg from the downpipe its almost as if i chopped my entire exhaust off from the downpipe
Do you guys get a fine for doing this? isn't that illegal? In Germany they wil confiscate your car right on place and you will be towed and get a huge fine. secound you have to replace the DP and do a certified test to proof they are back inside. which is also expensive.
Hello , nice hack 😁, How did you get around the Check engine light "code p0420" ? did you add an O2 sensor spacer, a mini cat or the resistor & capacitor trick? I really want to know what works with these N55 engines, your help will be greatly appreciated .
People, not hating on this guy BUT do not do this. These stock downpipes sell at least for $600 used. Check eBay for sold downpipes. You make better profit buying ARM or VRSF 3 inch, then selling the stock downpipes. Actually, you make double the money which is like $300.
Good idea, bad idea. Aftermarket downpipes is a larger diameter pipe over stock. Thats how power is increased with reducing back pressure. This will have minimal effect over true downpipes.
Thisguy Shorty thats what stock is on the N55. I had my cat out the other day right beside a racedynamics one. The aftermarket actually tend to be smaller. By a lot actually. Pretty sure stock is actually 3.5” already MAYBE even larger
Thisguy Shorty it’s actually not even hard to find this out. Just google vrsf downpipe vs stock. The vrsf is basically a straight through pipe. If anything it would be quieter
What in the holy f*ck?!?! My advice to anyone looking at this and getting ideas, DO NOT DO THIS. Getting the cat removed with probably like 40% of the cost of that cat you just ruined... You are drilling though something very expensive(even in scraps) to have cash?
John John I understand it's $900 new from bmw, but no one is going to pay $900 for a used cat. So the value of the cat is probably $300 if you where to sell it. Because even NEW aftermarket cats sell for $300+. I can't imagine anyone wanting to gamble and buy a used cat when they can buy a new one with warranty from a aftermarket supplier at the same cost.
Damn, you guys really care that little for other people's respiratory health, that you would modify your car to produce drastically more toxic gases for the sake of a few HP?
I would expect this from someone using glow shift gauges and stick on shifter paddles. Keep up the good work.
To each their own man, but you just smoked a $1000 cat to save $300.

More than $300 if you have an xi

These cats sell for £400 at the moment xD about $550 scrap value :P

Right to the point. Great video
@FastestM Hi, have you had any problems after this mod? Some engine lights or something? Thanks
Does your check engine light come on after you did that?
4:30 😂😂
lmaooooo
“this fucking mask doesn’t do shit”😂😂
LOL
The only reason I would still get new ones is to free up some space down there the oem are huge for future maintenance like turbos etc
I did it on FBO N55 today and unlocked rough idle mode :D I guess o2 sensors freaked out. Any ideas? Should I adapt the sensors or so
Mhd tune or bm3 tune o2 will freak out if you don’t tune it
Have any more videos of what it sounds like?

It will give a check engine

Really enjoyed the vid Ima gut out my turbo down pipe
Hi! how did you code the arrow test in the speedometer?
Could've sold those downpipes for atleast $700 and bought catless ones for $300

I'm thinking about doing this because I have an xi and you have to drop the subframe just to install new downpipes.
Did you end up doing it?
@@alminsmajkan7040 it can't be done on an e90 xi, the downpipes are shaped differently
Guys 😂! DON’T DO THIS! Just buy a catless down pipe from eBay for 100-200$ and keep your catted down pipe for later in case you need it. Or just sell your good catted down pipe for 500$ or more to some idiot that ruined there’s doing this. This is a 1000$+ part to replace if you require it later on.
$479 for catted high flow dp. Not sure why someone would buy oem that cost double a more efficient aftermarket one
This is worth it on a Xi. Especially because if you get vrsf or any name brand you have to literally hammer it almost shut to make it fit. Not worth buying something new just to bend it and hammer it into place.. and that 3” inch becomes more like a 2”
Keep seeing Xi related comments can you explain how the cat setup is different on our cars
@@razorkid456 cat setup isnt really different the bolts to remove the stock cat are just too hard to get to with the xdrive parts in the way
@@razorkid456 The all wheel drive subframe is different on the x drive models. Therefore the downpipe is positioned at a different angle.
Hey bro I have a 2011 bmw 335i xdrive can I do that to my downpipe and plus I have a meistershaft exhaust and cold air intake
Dont die bro hahaha and rev that shit to make sure all the cat practicals are out
Not bad but on e series n55 goes to a dual out let would it still be possible todo
Any video with the sound before after
So It's works ? It is possible to map tune?
Marcowy yes this definitely works, it becomes a “catless downpipe”...I never realized it would be this easy though honestly. Only downside is you can’t go back to stock if necessary for emissions without buying another OEM downpipe but that doesn’t matter in every state/situation.
No check engine light after ?
Dose it make it pop more?
Any problems or CEL after a few months of use like this? Have a f30 335xi and very curious to your experience with your car after doing this?
Aguas you will obviously get a cel because you have no cats, but a simple tune will clear it
@@Fastest__M do you get any drone noise? Im thinking of doing this to my audi so i can go stage 2
How many downpipes on your car bro
A bro a you in Los Angeles or by I need mine done to I have a 335xi coupe
Thank you
what brand rims are those and size?
Please help i gutted my cats today and for some reason when i put everything back together it sounds almost as if my car sound is exiting from the downpipe instead of the rear exhaust tips

The end 😂😂😂
You can see the gold flakes with the flashlight 😂
name from the paddle shifters?! Thanks :D
Dam you still got those apex wheels
Only worth it if you are already planning on buying a new catalytic converter anyways and gutting out the old one.
Isn't the material in the cat extremely toxic?
yea manufacturers should really should stop putting these things on cars
😂🥲😂 the ending tho
Any lights ?
Yeah I got the headlight taillights etc but to what you are asking yes you will get a check engine light unless you tune the car
Homie said sell the dust for $20 lmao
If that mask cant keep out cat converter dust how tf they want it to keep covid out tho
Did you say "you fucking died."
Do you guys get a fine for doing this? isn't that illegal?

Or you can do what I suggested my friend do, rent out stock downpipes for people who need smog 😂.
Try that here in Nazifornia, you will get a misdemeanor atleast 🤣
I was just thinking about that. How the fuck do I get smog in ca.I guess I’ll just buy a catless and swap in the other on the day I need to
If you run a stage 2 tune, it won't throw any codes for emissions
😂😂 I bet u got a better mask now lol!!!
And stay 6ft away
best vid on yout7ube LMAO
Good grief dude!
You mean to tell me the cat has all that shit blocking airflow?? Wtf
can you do mines
Good idea, bad idea.
Aftermarket downpipes is a larger diameter pipe over stock. Thats how power is increased with reducing back pressure. This will have minimal effect over true downpipes.
Thisguy Shorty any Aftermarket downpipe will have to connect to the stock exhaust so the connection will still be the same size
@@Fastest__M
Not necessarily.
I have 3" catless downpipes reduced to 2.5" for the stock mid pipes.
Look at the VRSF ones.
Thisguy Shorty thats what stock is on the N55. I had my cat out the other day right beside a racedynamics one. The aftermarket actually tend to be smaller. By a lot actually. Pretty sure stock is actually 3.5” already MAYBE even larger
Thisguy Shorty it’s actually not even hard to find this out. Just google vrsf downpipe vs stock. The vrsf is basically a straight through pipe. If anything it would be quieter
Lmao 50 years
The ending lol. Them masks don't 😷 do shit 🤣🤣😂😂😂🤣🤣
You could have sold that cat and bought a nice downpipe for literally same money as cat is worth. But this works i guess
What in the holy f*ck?!?!
My advice to anyone looking at this and getting ideas, DO NOT DO THIS. Getting the cat removed with probably like 40% of the cost of that cat you just ruined... You are drilling though something very expensive(even in scraps) to have cash?
Guys don’t do this take off your oem cat sell it for twice the price of a catless down pipe and coke out on top
😂 😂 😂 😂
😆😁
It messes up the smooth drivability tho
if you don't tune it
Cat is basically asbestos i think. This guy will get cancer lol
Ruined a 900$ cat vs a 285$ catless dp.
