For those looking to crank it to 11 with no intention of turning it down, the AWE Track Edition is your dose of steel. The Track Edition retains all of the precision engineering from the Touring Edition, and the bullet-style resonator in the mid-pipe, minus AWE's drone-canceling 180 Technology ® resonators in the rear. The result? Rumble with minimal filter, both in and out of the cabin, at all speeds. This version is known to get rowdy and may be too much for many--prepare yourself - and it can't be returned for sound preferences, you've been warned! (But AWE made it easy to turn it down if you need to with their Track-to-Touring conversion kit - a simple bolt-on so you don't have to buy a whole other kit if the Track Edition turns out to be a bit much. Nice!). Out back, the tips boast a 4” diameter, a stamped AWE logo, and double-walling to ensure a mirror finish even under hard usage. AWE tips are available in diamond black or chrome silver finish and are individually adjustable to allow depth into the bumper to be set according to personal taste. All this plus made-in-the-USA construction, 50 state emissions compliance, AWE's Fitment Guarantee, No Check Engine Light Guarantee, and the AWE Lifetime Warranty.
