specialB Posted April 13, 2010 Share Posted April 13, 2010 ..removed their exhaust from the DP back on track days? I have a catless UP and a high flow single cat DP with stock mid and cans, think the power gains would be worth the effort? Link to comment Share on other sites More sharing options...
executor485 Posted April 13, 2010 Share Posted April 13, 2010 Not a pro by any means... But the "power gains" would be minimal, and you would need to be tuned for it. A 3" exhaust should have no issues with restrictions, and if you just want to be uber loud, take off the mufflers and have a blast If I pass you on the right, I'm flipping you off.

specialB Posted April 14, 2010 Author Share Posted April 14, 2010 well the up and down pipe are 3" but the stock mid and Y is measly.. I've never heard it open exhaust yet lol there probably brutal Link to comment Share on other sites More sharing options...

Rexwagon Posted April 16, 2010 Share Posted April 16, 2010 I used to take mine off of my wrx. just straight downpipe. Other than it being very very very loud. i noticed it had a little extra up top. thats about it. Link to comment Share on other sites More sharing options...
snow05gtRI Posted April 16, 2010 Share Posted April 16, 2010 i dont think you would need to be retuned. its just the catback. Link to comment Share on other sites More sharing options...
LIZARD Posted April 16, 2010 Share Posted April 16, 2010 Nah, no re-tune, just GE-TurboFan Jet Engine loudness with some flames shooting out the underside. Stage2.5376, TDC ProTune,blah blah blahhhh and....Alky/H20 injection Link to comment Share on other sites More sharing options...

peteyjr Posted April 20, 2010 Share Posted April 20, 2010 My autocross buddy has a WRX without mufflers and its way loud, annoying if you ask me. He had infamous redo his tune and he claims it really improved the power band Link to comment Share on other sites More sharing options...
