Some one gave me this...

"Ya I bought one of those as well, I thought everything would fit except as you know by now your new header is about 3" longer than your old one. I tried to modify a test pipe to fill the gap where the cat is supposed to be, but it didn't work due to slight angle that flange is on. I ended up ditching any form of cat and cut the end off of my catback in order to weld a piece of pipe from the doughnut flange to my catback. It looks like hell and performance isn't what it should be because the muffler shop didn't even try to match the angle and just crush bent a short length of pipe."

I just bought the JDM DC header, and I have a SMSP high flow cat coming for my R...wondering if this is true? Are things going to be messed up or is the cat going to fit correctly? Anybody heard of this??

BTW, here's some eye candy even though most of you know what it looks like...it won't look like this for long though...sigh....

 

Mine fit perfectly. Are you sure that the one guy who's complaining didn't get a different model DC, I know that certain models have different header lengths, but I'm not sure as to which ones.

 

Your suspicions are well founded my friend. What I forgot to tell Justin is that I am using it on a 95' GS-R and connected it to a Greddy Evo exhaust. Now then, do you think that my problem would be solved with a 2.5" carsound cat meant for a Type-R? I wonder if my length might still be a bit off due to my Evo being for a GS-R. I may have been better off with a Type-R cat and Cat-back to match everything up? What do you guys think? ?

 

Well that changes things then....the GSR cat is shorter than the Type R's...hence why everything was off....lol, now it makes a bit more sense...I'd still like to hear if anyone had problems.

Aaaand, the type R header is longer....haha, the devil is in the details...

 

Both I and my brother have run your exact intended setup (DC JDM 4-1 with SMSP Carsound), and have have no fitment problems at all. The one thing that both of us did choose to do, however, was to remove the ridiculously small bottleneck at the cat/B-pipe flange on the exhaust and replace it with a tapered 2.5">2.25" reducer.

 

It is indeed! You see my GS-R header is actually quite a bit sahorter than yours is, so my JDM header is actually about 7" too long! To add to this I believe that a catback for a GS-R is longer than a Type-R's to help make up for the shorter header. And although my cat may be longer than yours, there was only about a 4" gap between header and exhaust once the doughnut was put on. I suspect that your cat is a bit longer than that? I think it is. Anyway that meant that there was no way that any cat would fit, the flanges themselves are almost 1" thick. So piece of pipe it is. I typing this I think that I may have come up with a solution for my own problem. I Think that I will get a 2.5" cat meant for a Type-R and then just modify my cat-back to fit.

Sorry to take over your thread with none Type-R material, I just wanted to give you the full picture of what I've had to deal with and help find a solution to my problem. It sounds like everything should work out fine for your setup. If only I had started with an R from the start none of this would have happened. Good Luck, you lucky bastard!

 

LOL, nothing to be sorry for man...now I know everything will be all right since I can't check for another 3 weeks. It would have sucked because I have everything lined up and ready to go on...but know I know it'll all work.

 

Well, I'm running a Thermal R&D exhaust not the stock exhaust...I know, this is going from 2.5" down to 2.25" and I know I am totally shooting myself in the foot but it's all I could get for now. This is all just a hold over until SMSP or Hytech.

Just curious as to why you decided on this header Vs. say a comptech race or saving up for a Hytech/Smsp?

I did it for two reasons: 1. I hit a manhole cover and needed a header in a hurry and SMSP was in the process of changing some equipement. 2. It was fairly cheap ~$600 Canadian, which was almost totally covered by insurance. Hytech was a little too expensive at $1200 American!

After seeing the results from the Titan Motorsports header test, it's a wonder why a lot more people aren't buying this header. In case you missed it: It's dirt cheap and flows outstandingly well.

Of course there is that little issue with ground clearance.

 

Yep, what Kendall said...I only paid 335 shipped for it in stainless steel, brand new, so it was dirt cheap as mentioned...

 

haha i paid 280, so 300 with shipping in ceramic, **** 35$ for bling!
i also had to do a carsound hi flow cat with a reducer by smsp from 2.5'' to 2.25'' to hook up to my dc exhaust.. but this is only because im waiting a couple of years to build my motor and once i do i want custom smsp header back on it and it wont see streets nor emissions by then.

It's not about bling at all...I am the last person to buy something because of bling factor, believe me....Ceramic is heavier, it gets hotter, and it cracks and will rust after a year or two or three....so why do it half assed? I don't want to have to buy it again in 2 or 3 years...even though this is just a hold me over until SMSP's full setup....I do it right the first time.

 

This header is at my girlfriend's house so excuse these changing questions but....there's no gasket or bolts with this header...I thought they came with them...this is the first header I've purchased...should they be there? And if they aren't, where can I ge them?

 

i wasnt aware of that, i don't think mine will ever rust i dont use my car alot. one things for sure i know no headers that come with bolts, use the ones already on the car, they should work

hehe, just checking...this is my first time ever buying something like this...

 

For the gasket, pick up a S2000 2.5 exh gasket. The round one, should be about $20. You can also use a early model,93-96 or so Legend gasket. Not sure on the exact part #'s.

 

if you need a gasket i have one 2.5'' i could sell you for like 10$ shipped

 

Use longer bolts and washers.

I will let you know if I need that very soon...

 

im also gona be installing a header for the first time this weekend. Im wondering if i should get new set of bolts/washer or just re-used the older ones?

 

I wondered the same thing...re-use the stock ones unless they are rusted and corroded.
