Only on the car for 8 days. The sound at WOT is more aggressive than I prefer, but performance gains are certainly there. I had AA ceramic coat the tips black to look like the Sport Line exhaust for an additional $150 charge.
I spent $800 on the exhaust including the black ceramic coated tips for just over a week of use, so this is a good bit of saving over retail at only $600 plus shipping. Local pickup in the Northern VA area would be even better.
