Catback system

[zippymedic]

I want to give my 97 V6 camaro the low rumble sound of the V8s, What Catback system is the best and most affordible, & do I need the 2.5 or 3". Also, is this just sound or does it add horsepower as well?

I'd suggest a flowmaster 80 series muffler and 2.5in pipe

This should be in the Exhaust forum. The best borla, a good sounding affordible system Flowmaster. And yes you can gain noticalbe hp increases as well. You can also do a search in the exhaust forum and find many different sound clips of different catback systems. And by the way you will never get the sound of a v8 from a v6 but you can make a v6 sound really good. Also you can go with what ever size you what i prefer 3in it flows better.
