I want to get a cat back exhaust. I dont want something really loud. I realize everything will be much louder than stock. I heard Greddy is good? How much power do you think this would add?

 

Why don't you get a custom 3 inch catback which will add more horsepower and cost around the same amount.

 

I have the Cattman full catback exhaust with the factory muffler and it is very quite...almost stock sounding. But you can tell it is aftermarket only when i get on it.

 

Hmm LatinMax.. how is it a full catback with a factory muffler?? More like Cattman cat and pipe to factory muffler hehe

CASS98SE : You could take the Brullen route (they have done lots of custom work for the local guys here). http://www.brullenexhaust.com/

Unfortunately, I went after airflow and just went for a straight-thru : no dyno results yet, but you can check out the noise and the sound of no traction at members.rogers.com/xfire/race027.mov If anyone is interested, that's the sound of a 2.5" exhaust w/Carsound high flow cat, 3" magnaflow resonator, and a dynomax ultraflo muffler (commonly used as resonators I hear). (I'm the silver one, the other guy is a 2k2 6-spd w/exhaust only I believe)
