A 3” and 2.5” T304L stainless steel configuration designed perfectly for the GLI’s factory downpipe. With zero filter, the Non-Resonated Track Edition is the perfect configuration for owners looking to add personality to their GLI while freeing up power and torque. Note: This Track Edition was designed for the stock downpipe. If you already have or plan to install a downpipe, we recommend the Touring Edition for a drone-free experience. Track Editions can not be returned for sound preference. 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.
