I started with a cat back Dual exhaust Moto Blue kit. Still as quiet as stock. Then I took the muffler off and stuck a Y pipe in its place. Still not much different. So now this past weekend, I took off the kitty. So now its straight piped with duals. I drove it to work today to see how it sounded. Holy crap its loud when you floor it. I couldn't stop doing it. Had people looking at me, Of course I love that. Sounds a little louder at idle. But is great at cruising. But when you nail it, you definatly get looks.:grd:
