I have a GReddy Evo too. Frankly, I love the fact that it's quieter and lower in tone than stock @ idle. And, when let loose at WOT, it actually sounds like impressive and powerful, not tinny and high pitched like most straight-through cannisters that I've heard.
Only complaint: Last night I set off my THIRD car alarm by exhaust note alone. First time I set off the alarm of a 30th Ann. Camero SS, so it was understandable why the guy's alarm would have been extra sensitive. The other two were ricers that decided to park next to me, so I didn't feel as bad... in fact... I was rather amused at myself
It's a huge tip, but it sits right at the bumper, which is really nice, and it weighs like 20-30% less than stock, too.
Though, the tone did get a little more ricey with the install of an aftermarket cat...
