AWE’s second-generation Track Edition Cat Back takes all of the precision engineering and performance of its SwitchPath™ counterpart, minus the valved muffler in the rear. The result is a constant “valve open” mode, at an affordable price. If you're craving rich and rowdy tones at all times, and a hefty 22.5lb weight savings, this is your dose of steel. Handcrafted from U.S.-sourced .065" wall T304L stainless steel, in house, at AWE world HQ. Featuring a unified design for OPF euro and non-euro spec cars, 50-state legal Cat Back design (perfect tone with all catalysts intact!), Precision-engineered X-pipe to unlock a clean S55 tone, 3” CNC mandrel-bent Cat Back configuration, and max gains of 12 hp and 16 lb-ft of torque at the wheels. Comes complete with AWE valve simulators to accommodate your factory exhaust valve motors, 102mm double-walled, slash-cut tips, and flaunts AWE's No Check Engine Light Guarantee, Perfect Fitment Guarantee, and AWE Lifetime Exhaust Warranty. Note: This version is known to get rowdy, and may be too much for many. For that reason, this particular version cannot be returned due to sound preference. Prepare yourself (Sport+ mode can be pretty raucous)!
