AWE track is a muffler delete. It does drone at certain rpms going up hill. I love how I have the heavy metal blasting and I can rip around and still hear the nasty exhaust. It also looks much cleaner up there with no mufflers. Saves only 10-12lbs surprisingly over my stock NON-NPP suitcase but at least it's something, if you're counting. Honestly, if I was afraid of drone I would leave it stock. My LT1 is my fun car. 100% pleasure. Hell on wheels. Bring on the drone. When I go to work, kids need to go somewhere or I want to have a conversation (LOL)...I'll be in the Honda
