Hey all...

I'm looking for a test/cat delete pipe that would be good for an HKS exhaust set up. I have a Hi Power exhaust and soon to get a HKS downpipe. Both of the diameter's on these pipes are under 3" but most test pipes only come in 3".

Are there any pipes out on the market that would be good for the HKS exhaust set up?

 

so basically you want a 2.5" test pipe
UR makes one
you can get them from here(get with gaskets...its easier lol)....GREAT service and FAST shipping:

I think most 3" test pipe's will even work with the stock dp and cb and they're only 2.25". I don't think it has anything to do with the pipe diameter, it's all about the flanges. Call one of the reputable dealers and speak with a professional.

 

go to a muffler and have one made. a test pipe is a pipe, no diff who or what its made of

 

Call Ultimate Racing

 

cool..thanks a lot guys

 

Checkout the RRE rally cat.

 

You can use either the UR 2.5 inch or 3 inch test pipe - the holes are slotted on the flanges to allow mating to a variety of exhaust diameters.

My helix test pipe works great with hks exhaust and my 2.75inch tanabe dp!

 

^after researching, i was a bit unhappy that the HKS DP is only 2.5"...so Im also going with the Tanabe DP.

how much power did you gain with that set up?
