The gains are REALLY GOOD
vtec sounds sweeeeeeet
the installation was pretty smooth....Had to go buy longer bolts for the header to cat connection.

The gains feel like adding an AEM CAI to a stock motor. I am still using my stock exhuast because fedex is late 4 days on my APEX N1...Once I get that on, I bet the gains will be better. geocities sucks for picture links so Some pictures will be posted on my site soon.

Future modification is to port the primaries, smooth out the weld on the Inner cat/exhuast flange, jet hot coat, and get a reducer adapter for my N1.

 

what was the length of your custom cat - i ask cause I got the spoon header, but need a custom cat, and i have heard the '00-'01 tegs (GSR) have a 2 inch longer cat (pushing/make the mid pipe sit 2 inches farther back/2 inches shorter)Please letme know, i could greatly use your help - thanks - Greg

 

Minty, shoot me an IM and let em know the length of the bolts you got. I will try and start including those in the package to help others out.

 

why didn't you do this before installing?

 

Especially the Jet hot that we offered at a discount as a special to group buy members. We get the 2000 degree flat black Jet hot done for costomers that buy the header for $180 shipped.

2 Guys actually had us ship them direct to Jet hot for them.

 

I did not get my done with Jet hot because I want to weld the primaries from the out side, then knock down the welds on the inside of the primaries. Then I'll have it coated (it also helps that my uncle owns a local powder coat shop that will do it for free ). If i had it coated before i got it, then the coating would have to come off so I could weld the out side of primaries.

Sounds like a good reason to me

Let me know hwo the modifications go.

 

No, here's the deal. all the GSR cats are the same length. The '96-99 GSR header is 4" shorter than the USDM ITR header, and of course the exhaust is 4" longer to compensate. The '00-01 GSR's use the USDM ITR header, so their exhaust is 4" shorter to compensate for the header length.

HTH, -C

 

TypeC: Thank you for clearing that up. So when using a JDM 4-1 + CarSound cat designed for the USDM ITR, instead of looking for a 00-01 GS-R exhaust we can use any USDM ITR-application?

 

D i ran out of funds for the extra modifications. Soon tho, soon.

Carlex: Thanks for the hook up. Oh btw, u should advise the buyers they need longer bolts for the header to cat connection

 

Actually what happened with the 00-01 GSR's is that they decided to use the same length header cat and B pipe as the ITR GS RS and LS.
So basically all 00-01 Integras use the same length header cat and B pipe
The 94-99 GSR has the same length B pipe as the JDM ITR

For a JDM Header on a 94-99 GSR or 97-01 ITR (WITH JDM B PIPE) you use a 12" long cat
For a JDM Header on a 00-01 GSR, a 97-01 ITR (WITH USDM B PIPE) or a Civic SI you use a longer cat of about 16.75"-17"s

yeah, that's what I said. Since the GSR is using the ITR header (so they say), then the exhausts are going to be the same length. 12" cat with USDM '94-99 GSR exhaust would work then (too bad I extended my ITR exhaust to meet the GSR header).

I don't know why they just didn't give all the tegs the same exhaust (USDM ITR exhaust) and give the ITR's the JDM 4-1. blah

 

where did you guys buy your JDM 4-1 headers w/Carsound cat ,and the rest of the flanges,and accessories to bolt the headers on?what are the price you guys got on these?and what do i need to do to get it bolt on my car?plmk..thanks

 

I am insearch of headers help me out.. so far i like the JDM ITR 4-1 over the DC JDM 4-1..what do you guys think..thanks

 

I got the JDM header from Carlex on that group buy that was a while ago. It came out to around 650 dollars for the carsound cat, header, and all the flanges allready welded to the cat so all you have to do is bolt it up to the ITR. Only thing i need to buy is a new header gasket and I'm all set (besides rewelding the primaries and power coating it).

ohk koo i might get it from carlex as soon as he reply to my IM ..how much is it extra to get it power coated..plmk..thanks

 

I don't know if you can get in with the jet hot he is offering, I think it was for the group buy people only. I am getting mine done for free because my uncle owns a powder coating shop and he said he'd shoot it for me.

Jet Hot deal is good for anyone that buys a header now that we have that option.

Asspenny, call Steve at 615-907-6650 I think we owe you that gasket. We will get you one regardless.

 

I had the primaries ported out a bit to smooth down the welds. We didn't have to re-weld it on the outside , as we got the welds smoothed out just enough, leaving enough material for strength but flat enough to help air flow. The finished product looked very nice, and wasn't very difficult at all. I guess if you weld it on the outside you can remove more material, but I am not sure if that is really necessary.

Calex, I got the donut and the gasket that goes between the cat and the stock exhaust, I did not know the buy included the header gasket (if that is what its called, it goest between the head and the header). If so, kewl, just put it in with the JDM hanger when that comes in that I ordered.

JSIR, I am going to weld the outside also, because I have access to a mig & tig welder so I can do it no problem. Plus I would rather weld it up now, then finding it cracked 5 months down the road from me cutting some of the weld out. I'll post some pictures up when I do this.

hey - thank you TypeRmsm and Type C for clearing that up for me sorry my mistake , i got all confused when the acura dealer told me the cats had different part numbers, i thought only the cats were different (dumb excuse for a dumbass - me) aaaa... now i feel much better about ordering a custom cat - but now - whose got the longer bolts, i wanna try and get my header on before my next autoX (not until 9/22 )

 

oops I was referring to the donut gasket. Not hgeader gaskets included as they are not neccessary on mst of the cars. No need on a 2001 R . . .

 

Thats kewl. BTW, thanks for the great buy and the awsome customer service. You guys rock. Here are some pictures of the header and cat stuck together (no bolts).

So do the 00-01 GS-Rs also have the same length header, cat, and B pipe as 94-99 RS/GS/LS/Type R?

-buji

 

If anyone else decides to get this header cat combo, remember to buy longer bolts and a couple washers so that the header can connect to the cat. Look up at asspenny's pix. You will need longer bolts where the header connects to the cat.

Over all, good set up, but I need some cams and tuning. lost a lot of low end with this and my N1
