Is it a gain to just go with a true 3inch like Borla or B&B?
Cudajon said:I've heard this too, I think fstjack tested it out and its true... Borla is a 2.5 like the stock one, and I'm not sure about the B&B.
I'm probably going to buy this http://www.aeroexhaust.com/true_dual_muffler_248.html and have someone build me a true 3" dual system.
