Remus 2013 Audi S3 Sedan Quattro 2.0L (CJXc) Axle Back Exhaust (Tail Pipes Req)

In axle-back form, the SwitchPath™ retains the M5’s factory mid-section, coming in right at the rear axle. The AWE SwitchPath™ Axle Back Exhaust maintains a 3” diameter, shaves weight from the rear, and retains the factory valve behavior. Available separately are the AWE Performance Mid Pipes to replace the factory mid section with a 3” stainless steel X-pipe, mating to the factory Axle Back (or AWE Axle Back, to make a full cat back). And if you’re not ready to do the mid-pipes, no sweat – AWE engineered the Exhaust Suite for the M5 as a completely modular configuration that allows you to do just that, at any time. Simply add the desired configuration to your cart, and roar away. All tip options are AWE’s 4″ slash-cut design, and include the AWE logo and double-walling to ensure a mirror finish even under hard usage. All tips are individually adjustable, allowing depth into the bumper to be set according to personal taste.Important fitment notes: If you’re equipping the Performance Mid Pipes or an Axle Back, cutting will be required. The Performance Mid Pipes + Axle Back installed together will not require cutting.
