How To Install an Exhaust Header Acura Integra 1990-2001
ฝัง
- เผยแพร่เมื่อ 17 ก.ย. 2024
- I've had this DC sport header for more than 10 years waiting for the day I got this car. The day has come and in this video I install this header onto my new GSR.
I've listed coverage of all Integras from 1990-2001 because the engines, even the non VTEC engines, are similar enough where the information covered will apply even though this is technically specific to the 2001 GSR model.

That click sound when a bolt comes loose, is the most satisfying
vadim6385 yes it's amazing haha. Especially cylinder head bolts they let out a massive click lol!
All that pressure being released after so many years of it being fastened
"Because I can, and you're going to watch the video."
Eric, you're turning into Apple lol
Eric I love your lack of bullshit, never change man
Such a great car. I remember when I first installed my DC Sports header...it pulled to redline so much quicker. Thanks for the great video
My eyes are taped open and I am strapped to this chair just to watch the video! lol This brings back memories some kid at school 15 yrs ago, installed a header on a integra I remember helping them.
Great video Eric! Just a quick tip for you. I always use 22 mm tools on o2 sensors. They fit more snugly than 7/8". 7/8" tools are actually 22,225 mm. And maybe because here in Sweden we threw our standard tool sets in the trash for like 20 years ago. They just never get used.
I'll keep that in mind. Thanks for the recommendation.
I'm currently restoring a 2001 GSR, and your Integra videos are filled with so many useful nuggets of info. Thanks, Eric! Cheers.
I'm never going to own or work on a Acura Integra 1990-2001, why am I watching?! Because its entertaining AF is why!
And because Eric made you.
he made me
TempGuest7 do you mean 94-01?
Before I finish the episode, I am guessing you may not have felt much of a difference. Though that said, since the old one is double walled and this one is not, you have more flow in potential, but I think you may run into the issue I have with my car. I replaced my stock manifold (on a 1992 Honda Civic DX mind you) which was a factory 4 into 1 that was double walled with a tri-y (4-2-1) stainless header. I did notice it changed the torque curve a bit, but with the factory exhaust I am not seeing much extra top end power. Did give my car a nice little burble though at idle, which is nice :) Now, when I replaced my roommate's exhaust in his 1999 Honda Civic Si, I installed a Megan Racing 4 into 1 header, high flow Magnaflow catalytic converter and 2.5 inch cat. back Yonaka exhaust...not only does it sound freaking amazing, he gained noticeable power through from just off idle all the way to 8,250 RPMs. Also, I might add, I am sooooo jealous that you got that GSR.
put long tube headers on my truck not too long ago but also put 2.5 inch straight pipes with flowmasters made a world of difference. that stock exhaust is killin header grains Eric.
Always learning something, always wrenching something and always a pleasure to watch your videos. Great video Eric. Have a nice day.
Gotta love these old Acuras. Looks easy to work on.
Have you guys thought about getting a light panel or two to sit on the floor behind Brian and shine up at the bottom of the cars? Sometimes it's hard to make out the details. Great video as always.
One thing i love about GSR's, Eric, wait for the short 3rd gear 😱
Damn wearing those gloves while test driving lol
i had a 93 integra, lowered, b18, exhaust and completely gutted interior. lots of people mocked how ghetto it looked until one flooded day in sunny sounth florida. cop cars were stuck and stalled, bmws floating in the corner... and my "shitty" little honda made it all the way home. at one point i even hit a spot with water going over the headlights and i even felt water pulling in through the huge intake i had, yet it all came out as vapor from the exhaust. that motor never died on me, it was such a beast!
Everyone loves their Integras. Others, just don't get it.
+Premium Nostalgia you had me at cookie.
Well don't offer unless you have enough for the entire class.....
Wow, that is the cleanest splash shield i have ever seen on an integra! Most are lucky to still have them, and the ones that remain are in tatters.
Thanks a bunch Eric. I really needed this video. I just found out my 99' GSR has a crack in the A pipe, and it's gonna need replacing. I love the videos keep them coming. Thanks again.
this is the very first mod i ever did on a car. pretty much started me on my career as a mechanic. good shit eric
You have no idea how excited I got when I saw a GSR video, I thought we're a year away from Integra videos.
Anyway, I've done headers on Integra's before and honestly without an intake, throttle body, intake manifold, and exhaust you won't feel much at all. Although after everything together, and a dyno tune you're looking at about 25-30 HP increase.
Correct me if I'm wrong but I've always went by the rule of 8-10% You need to have an 8-10% increase in power before you will actually feel a difference. Most of the time just a different sound will fool people into thinking it "feels" faster and /or more powerful. Great video!
I know you favor function over looks, but it would be nice to see you do a mild restoration on the Integra. It's a good start, seeing as its stock and in good mechanical shape. Moreover, it's unusual to see very clean, unmodified Integras. I think you'd enjoy it.
Your vigor already suits the purpose of a reliable beater.
"Why? because I can. And you're going to watch the video" Eric brought the funny. Also this makes me want another integra. I had 2 1990s one GS and one LS.
Eric you have the luck of the Irish. I have never had an exhaust that old just come apart easily. Thanks for video. Sam.
I have to agree, I was a little disappointed to miss out on a Fairmont video this morning, but Eric, you seem like you're in a much better mood in this video. I'm not sure when you recorded it, but if working on the Integra for a while saves you some stress, I'll take it.Keep up the awesome channel!
I wanted to bring the Integra up to speed so I took a break from the #FairmontProject to get that done. It's all good now and I'm back to work on the Ford. I love my job.
"Why? Because I can, and you're going to watch the video"
Truer words have never been spoken
"I'll be darned - it worked" ...the benefit of experience!
Hey Eric! I know you love new tires! I bet those would make that car feel goooooood. Always loved the integras
I agree. Holding off on that for now till I'm done spending money on the Fairmont.
Eric could you try doing a high flow cat? I"m kind of skeptic about power gains from exhaust on a stock motor, but I think replacing an old cat with a new high-flo one could make a noticeable difference.
+EricTheCarGuy Makes sense to me! You got three builds going on! The Integra, the Fairmont, and the fox body. You should check out Justin Dow with his channel World of Mopar. I feel like you guys would get along.
Hi Eric, greetings from Finland! You answered to me last time. It was in the Spring, thanks for that. Just like the way of how you are doing with Fairmont, Mustang and now with Integra GSR. It sounded, that you have maybe a bit wider rpm range in it at least, but there is four horns exhaust header bolted in instead of one or two anyway. Also that was very nice to hear that you are sometimes going to install all the remaining staff to the Mustang you have there. I have watched everything and I'll continue to watch in the future also.
Hello Finland! Thanks for the comment.
I was half expecting a loud deep cannon sound on start up. Kinda nice to actually hear one that wont make your ears bleed. lol
Rule #44: You never want to insert a dirty dipstick.
Flow wise it doesn't look like the factory header was much worse than the DC. But as anyone should know, just changing only the header on a otherwise stock exhaust (and even having the rest of the engine components stock) will almost always net a very very little gain. A header, now matter how good, it just one component to a much bigger system. Anyways, nice job Eric!
How did he know I was going to watch the video? EricTheCarGuy must be a genius.
I bought a 36 inch bolt cutter from Amazon warehouse for $23, they are normally about $50. Next time I need to cut a bolt, I'm going to try it. It's supposed to cut up to at least 3/4 bolts like butter. Tired of using a recipricating saw or taking a bath in sparks using the cut off wheel. That bolt cutter weighs about 9 pounds, I'm pretty sure it will do the job.
Known for years how to do this but just watched you do it and re-teach me cause it was just that interesting!
The Honda cast exhaust manifold is very close to a header as is. Impressively so. And it means it will last almost forever unlike that aftermarket header that will likely rust out in a couple years.
Dear Eric: your suppose to reset the ecu to read the new air flow coming in and exiting.
why? they are speed density not maf
Google it. Im not gonna explain it.
Eh, it'll learn it after a bit of driving. Resetting will make it learn faster.
@@mx3autozam Yes I believe they are. My b18a1 is.
Just a bit of advice, if you have exhaust work done at a shop, even if it's a reputable shop, always watch them do the work. I found this out the hard way as the shop decided to cut off the flange to the high flow cat converter and just weld the damn pipe all the way around. Now I have to cut the flange off of the new A pipe/flex pipe and fit it together with the old pipe as I don't have a welder myself. Otherwise this changing out the stock exhaust manifold over to a 4 to 1 racing exhaust header would be so much freaking easier...
That car needs a nice 2.25, or 2.5 exhaust. I put a 1 7/8" collectors, 2.5 flange header on my b18a1, and a 2.5 piped exhaust with no cat, 18" resonator, and N1 type muffler. It made a WORLD of difference.
Hi, Great video, when installing a set of headers and I'm using a new gastket, do I need to clean the exhaust ports on the heads? If so, what should I use to clean it?
Thanks.
Loved seeing this as the 3G Integra and 5G Civic are the '57 Chevys of my generation. Makes me want to finish up my '92 Si in the garage...
I've said that very thing about Integras. Weird.
eric, great job... thanks for the options!!! we need it!
The oxygen sensor socket tool with the slot in it is actually an install tool. It is not meant for breaking loose the sensor.
Thanks! The tips like how to get rusty or tricky bolts loose are super helpful.
ive had to replace sensors before because the threads rip off of 02 sensors, even with using penetrating oil, now every time i go to reuse the sensor, just as precaution so i dont have to replace it i touch it with MAP gas, then use an 02 sensor socket, works like a charm everytime
Ive done many of these That one came apart Easy. I only came here to count how many times Eric says Penetrating Oil.
On the O2 sensor it's critical. Those things just about weld themselves in place.
bentboybbz Is it hard without one of those huge car lifter things? I'm 16 and broke at the moment but I want the experience to install them myself and not hire someone. I have a couple jacks in the garage. How difficult would it be?
He needs to have sound effect for the penetrating oil.
One of my favorite videos! Watched it 2x and the 3rd today!
what Eric was trying to say is. Make sure your rod is protected by the rubber properly.
I believe you got real lucky with those bolt - unless somebody put anti seize on them - but no trouble and that's good - very surprised by that!!!
Honestly, I don't often have problems with them, but when I do.... Life sucks.
+EricTheCarGuy my one bolt snap off
Doing this job on a Type R in a bit. Using PB Blaster to installing Alpha V2 Skunk2 headers
Awesome! You should budget-blaze this thing out i.e. install an old crusty turbo from a saab, a plenum from a ford f150, injectors from a yamaha, etc.
I enjoy watching your videos but with the Fairmont project now going, I'm a little bummed that I woke up seeing this one. Hoping next week we get back to watching some Fairmont action!
Sorry to report we're taking a break from the Fairmont for a bit. I did however post a Fairmont video on ETCG1 Monday.
+EricTheCarGuy need time to think? Get your breathe back Eric?
Everything is well detailed and explained but the thing I don't like is if the mechanic doesn't take off his dirty greasy gloves and touch my steering wheel and actually test driving the car with his gloves still on. Lol
So good so far lol. I'm still the number one fan of this man Eric in terms of DIY. Very profesional in what he does best. Stay dirty :)
I hope you see this Eric. I installed an aftermarket header on my GSR with the new header gasket but it won’t stop leaking from the right side. I snugged and tightened all the bolts from the middle-outwards. I even tried reusing the old oem one but it still leaks and sounds like crap
As you said in a later video, just this part alone won't really help, the small gain won't be much unless you do more work to the exhaust, to the engine, to make it better use what the part can do for you. Despite what a lot of people seem to think, there's no one part you change to suddenly wake it up, you have to do a lot of things, each one only adding a little more power, to have it all ad up.
Thank for your honesty I bought turbo and skunk2 manifold for my rhd gsr I will wait to install a turbo kit with patience instead of the headers and manifold since is cheaper to do.
This is fantastic. Just a good old classic ETCG gettin it installed video.
If your nearest dyno is 4 hours drive away, that sounds like an opportunity to buy yourself a dyno!
Good morning Eric , as always great work on what you love with your passion of work . I must say there isn't many out there that go in this much details like yourself . Keek up the good work my friend . One day or you do now lol will walk into work and go wow and see in full detail what you have created :)
That OEM exhaust header was fairly well designed - although not equal length it's a long tube. I would be surprised if the aftermarket header would have made any difference for you.
Quick question, Eric. I'm about to do a header install and the previous owner's gasket shows an exhaust leak around cylinders 3 and 4. What precautions should I take before installing this header to my vehicle? Thanks!
You're losing 16lbs from the material change but you're also losing some power from the smaller pipe diameters. So your performance really didn't change but you did succeed in making the car look a little cleaner.
They're not smaller diameter pipes. The stock set up was double walled.
AND; smaller diameter primaries on a header do NOT mean loss of power. It means higher velocity flow, better scavenging, quicker throttle response... if tuned to intake primaries and motor displacement. Bigger is not better. there is only right or wrong.
does anyone else think Eric looks like George Clooney
I won't tell my wife or she might want to watch these videos too
lol
I'm thinking a metal hose clamp would prevent spreading of the o2 sensor socket with the slit in it. if that happened to be the only one you had.
Thanks, Eric! We want more GSR videos ...
I do have a few more for you.
I feel like if one had a full aftermarket exhaust installed along with other modifications to the car and then swapped from stock headers to these it might allow for better flow and more gains. I'd guess that doing this modification alone would be equivalent to installing a "cold air intake" on a stock engine - more capability for flow, but no immediate gains.
Also helps to do this when you are doing the partial or complete rebuild when the radiator is removed, but not everyone will be doing that. I know for sure though that doing this on an Eagle Talon 2nd gen is much easier than on Honda's and Acura's, as there's less crap in the way...
Thanks Eric. as always another interesting and instructional video.
Eric, They have a dyno at Turn in Concepts in Cinci. They do fantastic work.
I like your racing gloved you used during the test drive.
I have a 2000 gsr with a greddy header , you should go with a magnaflow high flow cat with 2.5 piping to a magnaflow muffler really great sound nothing raspy nor to loud I have no resonator
Thanks for the GSR video. I miss mine. There is a ton you can do to make this scream, get a high flow cat, and a cat back exhaust, cold air intake and tune it :)
I could also keep it stock and preserve a piece of Honda history. It would also be worth more that way down the road. I didn't toss the old manifold.
i like dc sport headers they are work the 300 or 400 bucks my dad bought a set for a j30 and they have almost 9 years on and they havent broke hey are amazing and give me alot of top end compare to stock
Great video, I have found it informative and entertaining. It's funny how you keep your safety glasses and nitrile gloves on for the test drive! Eric you're the best.
Funny guy at the start😅😅already forgot to pay attention in class🤣🤣
integra gsr... best car ever.
Yes, since this one is stock, and clean that would be a great choice
Long tube 4-2-1 header (hytech or replica) along with full 2.5" exhaust including the cat, with a well designed intake manifold and you may see a 10% increase in hp. I'm not surprised that you didn't feel any seat of the pants gain on that one. Nice video though :)
Thanks for more honda stuff. Would have spent 20 bucks and 20 minutes wrapping it personally. wrapping a header might be a good, cheap, fast, and somewhat smoky vid. look up either rockwool/'titanium' stuff, or use silicone spray with fiberglass type.
Coincidence i obtained the same header on the same day from a buddy of mine thanks Eric much love from sf bay area!
Comparing this test drive to the first one you did, at least to me it sounds like it's revving up quicker with the new header.
It's not. It might be a bit louder. I think the biggest gain is in the weight savings and it makes the engine compartment look better.
Agreed, regarding the weight saving.
12 point wrenches and sockets should only be used one 12 point bolts. And always use 6 point tools on Bleeder screws. Always!
I have a '96 Japanese Type R with 70k miles on it. I've changed the timing belt but not the water pump. Should I go back in and change that too? Too my knowledge it's never been changed before.
Thanks so much for all you do on the channel.
I bought a second hand one for cheap. It seems to be the same but the flange doesn't line up correctly. It's rotated the other way around and it is for a Civic. Got some welding to do
Damn Eric. I have not seen your videos lately and you drop some weight. 👍
Respect From Poland JDM Rules Love Honda
YOUR THE MAN ERIC
Nice! I'm not a Honda guy but thoroughly done and on down the road'ja go!
you sould put to the to the discretion the 2000 pontiac montana series. nice video keep the good work!
Supporting mods will help. A new intake, high flow cat and exhaust will really open up that airpump. Then you'll need fuel and a tune. And the suspension will feel soft. Blah blah bleh. Don't walk down that path haha.
Yea, still going down it with the Fairmont.
Eric, you should do a video on how to paint the valve cover gasket!!
It would be interesting to see how well the long O2-sensor socket would do if you put a hose clamp around it.
Great video! I've been seeing some good videos about removing rust by soaking parts in vinegar. Dirt cheap, and the rust seems to dissolve - good for things you can't take a wire brush to, like the inside of a gas tank.
I'll have to look into that.
I did the vinegar thing to try and get the collector studs out of the manifold on my old 97 F150. It didn't eat enough away to get them out (maybe it would have if I let them soak for days), but it definitely ate enough to show where the flanges end and the stud began. In the end it made torching them out simpler.
Just like the last motor I put "performance" parts on; I ignore the mfgr claims. If the parts I get jive with what I'm trying to shoot for in a build - fine, I put it in. I don't look for improvement. Only after MANY little "upgrades" here and there have added up - do I have what slowly becomes apparent as "an improvement". Polished ports, a new K&N air filter, a flowmaster exhaust, etc...I say - be patient and use your head. Only certain parts will make a noticeable difference right away; cam, bore/stroke+, etc.
DC sports manifolds were popular early on but the collector is crap. Many other (much more expensive) brands came out and fixed that. I bought one for my 98 civic ex. Its a slight improvement over stock but that's it. Regardless cool video that brought me back to when modding your car was easy. I now own an FA5 and nothing is easy or as cheap.
Eric another video
Repainting a rocker cover
just did this on my 97 last week with just the left front side jacked up off the ground and hand tools, was really easy but very uncomfortable
A day when You get Your "I'll need this one day" stuff from years ago, mount them, they fit and are aftermaket powerpart or factory new plus You found just the right bolts. Goddamn, the planets were inline and no one told me ?
1st time seeing a integra with all his plastic covers on, weird
weight loss is always important regardless of power or torque gain.
