Hmmm What You Guys Recommend?

[QRI05E]

while my car was on the hoist getting the oil changed, i noticed that from the stock dump-pipe i had a 3" stainless steel front pipe going in to a pissy little compliance cat (size of a bread roll) then 2 1/4" piping into another centre muffler then into the back muffler.... im assuming that the exhaust was changed cat back for compliancing... but you guys think cause of the cat n mufflers that it would be restrictive?? would a full 3" system make a difference in performance? what are your suggestions?

thanks for your input guys

Like the other guy said...yes simple as that! Buy a dump and a cat and a cat back and you are away

indeed.l the stock dump pipe is rancid! very restrictive especially when going for larger turbos etc.. 1st thing i would change on the exhaust.

No question.

Yea i knew i should upgrade the exhaust system... but what kind of power gains should i expect with the full exhaust and K&N air filter??? has anyone dynoed their stock R33 before and after exhaust??
