I can't decide which brand to go for. Which one of these sounds better overall? Any difference in performance? I bought a K&N intake for my '07 Silverado and i want a good exhaust setup for a nice in and out flow but also a noticeable difference in power. Any suggestions??
I have two questions first does anyone know a safe way to be able to fit 285s on my sierra its the classic body style and i have my keys all the way up and it barely fits my 265s :(, and second does anyone know hoe bad my gas milege would be if i ran a y pipe straights. i have a flowmaster and get about 14 around town. also how loud is it inside the cab with a y pipe ? Thanks alot guys !
