Hey I currently I have the HKS Hi-Power exhaust on my evo as well as the RMR downpipe. I eventually want to get another downpipe and I want a test pipe to go with it, which brand should I get that has the best craftsmanship and the most hp gain? And I also have to find out what downpipe will clear my RMR lower arm brace and what test pipes will bolt up to the HKS exhuast and downpipe.

 

Just curious, what's wrong with the RMR downpipe?

 

If your cat back and downpipe will bolt onto your stock exhaust, than any test pipe that bolt onto the stock exhaust will fit. I just purchased the a brand new apexi gt downpipe that elimates cat, I highly recommend and I only paid $205 shipped.

 

I have the same CatBack w/ a Perrin DP and a UR test pipe.

Test Pipe w/ mechanical fix, no cel, 27,000 miles. Cannot complain.

Perrin DP clears lower ties bars, great piece

Everything fits perfectly

 

did this combo create a CEL??

 

Nope, ive read many people have had them installed and have had no problems. Also has o2 bung so you dont have to drill.

 

can you mention some vendors at that low price?
thx

 

I got give the Perrin Downpipe and Testipe a big . I have the downpipe coated by Jet Hot. The fitment and the quality is awesome of both piece. Also no cel light for me either with the fix. PERRIN gets my big .

 

I like the WORKS because it comes already coated.
