wow...your setup sounds better than mine when I had the full system (S/R pipes & rear muffler).
1. you vid quality
2. your car pumps out a bit more hp than mine.
BTW, i'm sure your rear muffler has already broken in.
My S/R pipes might not be fully broken in yet because i drove it mostly in the city & not many time I could redline the car with it.
it sounds GREAT man. I'm envious :-)
