I'm almost interested in purchasing a pair of these mufflers and throwing them on. The only downside is the price of Borla mufflers because of their stainless steel contruction, and being left with them if I don't like the sound. Mainly, I want a sound that is not tinny at all, and is deeper than it is now. It sounds kind of like a really loud v6, or maybe even a straight 6. I don't know if you've ever heard a v6 with near open exhaust, but it doesn't sound quite like how I want my truck to sound. If these will make my exhaust note deeper I wil definitely look into buying them. On another note, all my exhaust pipe is 2 1/2", do you think that extra half inch would make much of a difference?
