I see many people considering changing the sound of their exhaust, but don't wan't to go all the way, or too loud. Here is a clip of my car. This is my LS2 with a resonator delete ONLY.

Just small additions.
Since these pics I only got 20% tint on the windows, which really brings out the Cyclone Gray. Hope you enjoyed!
