Great writeup! love the before and after videos--don't think anyone has taken the time to do that before. Looks like the perf exhaust doesn't have the exhaust flap to disable the driver side muffler on cold startup (judging by the fact that both exhausts had smoke coming out in the perf video vs just 1 in the stock cold start video).
