yeah, the difference in power will be minimal... either way it will stil have gains over stock, and my opinion on exhaust is get what you think sounds good, not looking for the most power. I think too many people try to squeeze horsepower out of aftercat systems and such, but it's a waste of time. The guy with 1000 bucks in exhaust could have bought a big bad set of heads and lit up some gm's world.... or hell even some cheaper exhaust and a nitrous kit!!!
