Guess they do both 2.5" and 3" systems? What's the benefit of 3 over 2.5? I'd guess the note is deeper and a bit louder, but are there significant performance benefits as well?
3" sounds great IMO however its more likely to drone, it's generally got no performance benefits unless you have a cam, forced induction or a LS3 motor. For a daily or street car a 2 1/2" is preferred.
When aftermarket headers/extractors are used you get a better a deeper note anyway from a 2 1/2" system
