I've got around $1500 to spend on a full exhaust system for my '01 ITR. I am really interested in Comptech's line. I was thinking about doing the comptech MIG header since from searching I found out that there's not much of a reason to spend the extra $ on the TIG. Then matching that up with a Carsound and finishing up with the Comptech SS catback. I love the sound of my car now with just an AEM CAI. My biggest concern is losing that great noise for a "ricer" sound. My questions: Would this system sound good if I'm going for something almost stock sounding? Does anyone have any sound clips of the comptech exhaust? Would my budget allow for this after install (assuming I don't install it)? Thanks guys.

The comptech full exhaust has a deeper sound than our stock exhaust. If I were you, I would spend an extra buck and get the SMSP or Hytech exhaust. You will make a lot more power and it will be right around your price range.

I have Comptech Cat-back and I really like the sound. LIke Haunt said, it has a deep sound and not too loud.

There was a video posted a while back. search for Thunderhill

what about the fujitsubo? i know that the sms is better, but maybe another alternative

Comptech SS exhast has a god sound. I just pt one on my car with the Comptech race header and Adapter to match them up. When you say Mig if you are referring to their USDM collector size header then you don't need a carsound cat. I would definitely recommedn the Race Header if you are willing to spend the money. Call the guys and ask them what they will do for you on a whole system (Race Header, Adapter, and SS Exhaust). Nate will likely answer the phone. Good guy, tell him Trey Sent you.

To comment on some other suggestions. My next choice of exhausts at this point would be the Fujitsubo RM-01a and SMSP new design. Both are similarly priced and some are even 2.5" and still quiet.

I have Comptech's intake/header/cat/exhaust on my car. Is not much louder than stock at idle with a deeper tone. Definitely louder (but not buzzy) at high rpms. I actually bought Comptech's silencer because car was a little too loud for me at 70mph+ cruising (I also have an ATS 4.9 final drive though, which does not help rpm-wise).

Good thinig about Comptech is that it is fairly cheap used because it does not have the JDM bling factor. My entire barely-used i/h/c/e system cost $950 and I got $400 for my stock system, giving an outlay of $550. Unless you are going to put trick cams in the car at some future point, I would not bother with $1k+ headers and exhausts.

Have to disagree with some of this. I think the most important factor in a header these days is that it have a 2.5" collector. It doesn't have to cost $1k to ahve a 2.5" collector but sofar the $900 range headers seem to be the biggest performers for modified cars.

That said I have an almost identicle setup as mentioned above I have the Comptech Race Header, adapter, SS Exhaust as well as the Icebox and am driving a ATS 4.9 FD. I actually find Highway speeds to be the least noticable part of the exhaust. It is pretty loud under low rpm accelleration. I do have a silencer on the way . . .

I've also got the same setup with a comptech intake/header/exhaust and random tech cat -- was thinking about putting the sliencer on -- also have FD from spoon -- so i'm trying to get some of the droning noises down as well. Was wondering how much of a difference it made for you?

Yeah, i agree with everyone else here.. its a much deeper tone.

The car is quieter with the silencer but not dramatically so. It takes the edge off the noise levels at high rpms. A nice side-effect is that it also got rid of an unrefined cheap-sounding blaring noise that this combination made at WOT.

I could not detect any decrease in power with the silencer (though I am sure a small amount may have been lost).

Comptech makes great products, but id get their race header like trey has, or at least one with a 2.5" collector. I was looking at exhausts the past month and wanted the Fujitsubo Rm-01a, but it was a bitch to get (massive backorders) and shipping was outrageous. I ended up spending extra on the mugen twinloop, and should have it installed with a T1R testpipe and DC JDM header in the next week.

Thanks for the input guys.

Two questions: Do they make a carsound cat that doesn't have a 2.5" inlet/outlet (one that would work with the Comptech header and exhaust)? Because wouldn't a carsound cat be better than the stock one?

Am I correct when I say that the Comptech race header is not street legal? So does it throw any codes and will it fail emissions?

Thanks again.

I would just keep the stock cat if you are getting the comptech header.

The race header is not street legal and it will not throw any codes. It will fail the visual part of emissions but might pass the sniffer.

It will likely throw the cat efficirency code if you car is using OBD2.

A code alone in some ststes is grounds for emissions failure.

If you use a cat, then it won't throw any codes. You may need an extension for your O2 sensor to reach because the header is longer.

If you get Comptech, I definitely would NOT get their regular mass market 4-2-1 header and 2.25" (Power Pro) exhaust on a Type R. Reason being that they don't do anything special for the Type R application and just use the same header and exhaust that they use for the LS. Even Comptech admitted that their full I/H/E setup only gained about 8whp on a Type R. They didn't design their mass market parts with the Type R in mind, because obviously there is a much bigger market with the LS and GS-R.

When I originally got the Comptech exhaust and layed it next to my stock ITR exhaust I found the ITR exhaust to be smoother and built better than the Comptech, same tubing diamter as well at 2.25". Obviously the exhaust ended up doing nothing for me performance-wise.

If you do go Comptech then for sure the race header, 2.5" cat, and 2.5" exhaust is going to be the best way to go for the Type R. Of course you also have many other options but if you must stay Comptech then that's going to be your option so that you don't throw your money away on parts that perform the same as the stock parts.

$1500 on exhaust? Go HyTech and don't look back.

The HyTech full exhaust (header-cat-bpipe-muffler) runs around $2000. But $1300 of that is just for the header.

ActiveAero

I'd go with an SMSP header then run a custom 2.5" mandrel bent exhaust with a resonator and quality muffler. KTeller8 does custom mandrel bent exhaust for our cars at very good prices. A full 2.5" mandrel bent exhaust with magnaflow resonator and Oval ES muffler is priced at $325 (aluminized, he does SS as well). Definitely go with a 2.5" collector header. They make more power for starters (alot more in SMSP's case) and you will kick yourself down the road if you ever want to install a set of cams.

You can't run a Cat with the Comptech Race Header unless you significantly modify the B-pipe on the exhaust. Just as you mentioned extending the O2 sensor wires you only have avout 5-6" for a Cat befoere the B-pipe. The Comptech Race exhaust bolts right to the Race header (no adapter needed).

I found the comptech exhaust to be much nice setup than stock. true 2.25" with no neckdowns like the stock exhaust and a much more free flowing muffler.

Trey

For a longer header like the race header I think modifying the b-pipe is somewhat of a given. If it's going to be completely bolt-on then of course the only exhaust you can use is the Comptech race exhaust, and in that case you can't use a cat which can be up to a $3,000 fine in many states. I know this is supposed to be a "race only" part but fact of the matter is that most people are looking to put these parts onto their daily drivers so sometimes other things have to be done.

Otherwise like most others have done with the SMSP or HyTech headers who did not get corresponding HyTech or SMSP exhausts, have the b-pipe chopped a couple inches shorter and use a Civic EX O2 extension plug from DC Sports. Then you keep a cat in the system so you are good with the law (if it applies in your area) and have no CEL and can use whatever other exhaust that won't be super loud like a race exhaust will. That's just a way to make this "race part" a little more street friendly since most in the market to buy this header will be putting it onto their daily driver and only a few will actually be using them on competition cars.

Asahi

There is an adapter for the Comptech Race header that allows it to be used with a stock length exhaust. This still does not fix the cat issue you have mentioned though so if you are definitely going to run a cart B-pipe modificatio is a given.

Wait . . .there is a O2 Wire exstension adapter?!? I just cut and soldered . . .got a part #?

SurferX

I lost the part number but Austin likely knows since he found out about it originally.

heres something you should be concerned about first, is $1500 worth for just a sound, if you're after performance, get 2.5" exhaust, toda or smsp header. smsp offers 2.5" exhaust at better price - the only bolt on exhaust i'd consider worthy out there. that would be the best of everything, so you'll save money in the long run - how? - you won't have to sell your comptech exhaust or header and loose money, you already have the best.

comptech exhaust/header isn't worth the money in my opinion over stock. - good quality exhaust minus oversized tip - worthy if your car doesn't have stock exhaust for whatever reason.
