For those who like it raw and rowdy, the Track Edition is for you. The Track Edition shares the same integrated H - pipe and precision engineering as its Touring Edition counterpart, minus AWEs patented drone - canceling solution, 180 Technology. In place of the 180 Technology resonators in the rear lies Track Edition straight sections. As a result, this version is known to get (really) rowdy in mid - range acceleration and deceleration and may be too much for many. Due to this reason, AWE Track Edition Exhausts cannot be returned based on sound preference. But fear not if after running the Track Edition you're feeling its a bit too much, AWE makes it easy to swap over to a Touring Edition with the Conversion Kit. Just bolt it on and tone it down a bit easy This Track Edition reuses the factory tips for that stealth look (and anything but that stealth sound).
