Installed a GYT-R slip-on exhaust (part #GYT-2C093-01-XX) on a 2008 R6. Did a video comparison between the stock titanium exhaust with the EXUP system, and the GYT-R slip-on without the EXUP or a power commander. Sorry...I realized I didn't rev it up enough with the stock exhaust till I had made the switch and watched the videos. Install took about 15 mins.
