I installed the exhaust a couple of days ago (without the optional front pipe). Here's a video of the cold start and a few drive by's.
When I first drove the car after the install I was not used to how loud it was on the inside of the car. This is mainly due to the fact that the stock exhaust made little to no noise as all of you sport owners know...
After driving a couple of days with it, I am really impressed. Love the deep sound, and crackles and pops here and there. Honestly I'm so excited to drive the car now and can't help but to pull through the gears all around town. Drone is also non-existent especially cruising along the highway at low engine load.
Customer support was excellent, Vincent was kind enough to follow up through the entire process. Highly recommend getting the 27WON exhaust!
