The Resonated Track Edition retains the same precision engineering of the rest of the family, with the addition of a resonated mid section right before the rear axle. This version is intended for those looking for a more sophisticated soundtrack with their factory downpipe, or for others who have an aftermarket downpipe that are looking for the “middle ground” on the volume scale. Note: The Resonated Track Edition is fit for both factory and aftermarket downpipes, but may be a bit rowdy for some downpipe-equipped cars. For this reason, choose wisely, as Track Editions can not be returned for sound preference. For a drone-free experience, go with the Touring Edition! But fear not – if after running the Track Edition you're feeling it’s 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! When it comes to tips, the Track Edition finishes off with 102mm slash-cut tips, featuring the AWE logo, so they know what team you're on. All tips are individually adjustable, allowing depth into the bumper to be set according to personal taste. They're also double walled to ensure a mirror finish - even under hard usage.
