i duno, i have a 3in. w/ no cat and a small resonator and my car is extremely quiet, much quieter than all the cars out there with just a muffler welded on....turbos act as resonators as well, so the car is much quieter than an NA car with a regular catback

 

good point. so would you go with hks or apex. i was looking at apex's n1 evo system and its cheaper than hks's hipower system. wut ar you runnin on yurs

 

if you want something max quiet blits tt is quiet.

 

honestly mine is just an ebay 3in. with a test pipe in place of the cat...my exhasut has a resonator..I get so many compliments on how quiet yet awesome it sounds at full throttle, i love it..

between apexi and hks they are both great brands, i believe hks is a little but more quality, but either way theyre both good choices, just get whatever you like best..

 

aight cool. im a bit short on money so im gonna go wit the apex n1evo, thanks for the help man.

 

I have the Apexi N1 exhaust on my car and it is not that loud and i think it sounds pretty nice with my GT28RS turbo. I don't think you'll have any complaints about it. Hks is always good too but just thought i would let you know what i have and I have no complaints about it at all.

 

cool , thanks

 

Garrett GT2540R is a MUST
