Hi , is it worth puting a cat back exhaust on the type r , it's about the performance not noise . Does anyone have proper dyno results for before and after gains?
Cheers

The cat back is more about the noise than the BHP.

BWAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAA


Lovely :thumbsup:

And I'm being serious!

Depends what power your running (i thought)?

e.g. i couldn't have the standard cat-back on my car because of the back pressure. NA though you should be fine whatever. The exhaust manifold is where all the powers at!

The Milltek made gains throughout the powerband when I tested mine, 3-5bhp. I felt a gain from the exhaust manifold (I had Tegiwa) like others said although the best gain i have to say was introducing the Mugen intake with scoops, the Tegiwa enclosed system would perform similar.

If youre after further gains, the RRC intake manifold gave really good top end gains and going further some of TDI's stage 2 cams will make the Type R fly!

The sound make it feel faster though :D

If you want power gain.. decat and race header, as said. This will give 15bhp ish on the top end but a massive increase in bhp and torque in the upper mid rpm range. At about 5500rpm you'll be up 20lbft and 40+bhp.

Didnt they make only a few horses more than the stage 1 cams at half the price?

Not road legal then though, right?
