OK...so I just put that down pipe on and 2 things....1. it feels like its touching the body of the car when I first accelerate and when I floor it, I can feel it whats the fix for that? Very annoying. 2. I dont like how the exhaust sounds it got louder and sounds like a beater lol kinda like an old 3.1 corsica I had for a work beater back in the day with no muffler just not as loud, how can I quiet it back down to near stock noise levels??
