i'm getting a buddy club spec 2 exhaust for my 99 DC4 and i'm wondering if anyone has tired an aftermarket hi-flow cat converter or a stock cat converter with their spec 2 exhaust? aftermarket cat converter as in OBX or Magnaflow. but i know a main concern would be the cat converter length might be too short which would hit the gas tank?

 

right now i got a tri-y header with welded test pipe (exhaust leaking from bad welds) hks hi flow mid pipe and yoanka catback. i'm switching over to something i've been wanting for a long time now

 

anyone?

Not sure that I understand your question. Are you asking if the length of the cat converter will effect wether the system will hit the gas tank or not?

If that is in fact your question, I didnt know it was possible for the exhaust system to hit the gas tank based on the length of the cat converter.

Am I missing something really obvious here?

 

i'm have concerns that the cat converter will be too short.
also i've looked all over the place and couldn't find the piping diameter of the exhaust.

 

I'm running a BC Spec 2 with a JDM length T1R racing converter. The spec 2's b-pipe is longer than a stock USDM b-pipe, thus you'll need a shorter cat. But with the tri-Y header you have, which looks to run longer than a stock manifold, I'm not too sure how short. IMO, I would get an adjustable testpipe.

 

thanks.. you know the piping diameter of the exhaust? 2.25? 2.5? for dc2 spec 2?

 

60mm

 

btw what headers are you running?

 

not to thread jack, but i have a kiddracing header for my 00 gsr and i'm getting a headache trying to figure out what to do with the cat/testpipe/resonator... needs to hook up to a 2.5in skunk exhaust. i'm trying to keep sound down some so i was thinking resonator, but what length should i order?

 

JDM 98 Spec 4-1


If the Skunk2 b-pipe is USDM length, then you need a USDM length testpipe (18"). I believe the KiddRacing header is a normal length header (same length as stock)

 

tusudo allso has a adj testpipe as well thats 2.5

 

are any of the test pipes resonated? if possible, im trying to keep noise down cuz the gsr is my dd

 

pretty sure ebay one's are
