Ok, so as soon as spring comes, I am about to drop more than I should on this thing, but I have one real question. I see people on here saying that the aftermarket exhaust systems arent adding any noticeable hp. So, my question is then, Why? If I am not going to gain any hp out of a new exhaust, why would I do this other than to make it louder. Maybe if I put new headers on it and what not, but that wouldnt happen in the forseable future. I like the idea of having all power I am going to have, yet still being 'sneaky'......perhaps someone could shed some light on this new guy, but if there is no advantage, I am going to keep the stock system.
