Thanks to AWEs drone-canceling 180 Technology and countless hours of R&D, we were able to craft a system for the SQ5 that enables perfect part throttle cruising when you want it, and a disobedient soundtrack when you're feeling a bit more aggressive. In other words, the AWE SQ5 Touring Edition Exhaust is the best of both worlds: SQ5. Unlocked: Featuring AWEs drone-canceling solution: 180 Technology Engineered around the SQ5s specific Tiptronic tuning Direct bolt-on Gains of 8 hp and 9 lb-ft of torque to the crank X-Pipe for enhanced exhaust scavenging and improved tone Available with chrome silver or diamond black adjustable quad outlet 102mm tips Crafted from 2.5 T304L stainless steel No CEL Guarantee Fitment Guarantee Lifetime Exhaust Warranty Since there is no independent control of the valves (except Sport mode which changes a number of other things), the AWE 180 Technology equipped exhaust responds to driver inputs seamlessly, removing the need for valving. 180 Technology is not the standard, typical approach to performance exhaust design. Through proprietary mathematical calculations, AWE engineers were able to create a sound cancellation resonator that definitively turns off the frequency where drone occurs. At the same time, while being able to squelch drone 100%, the resonator design is also providing a 100% straight through, full diameter flow for maximum performance. So, at part throttle, relaxed driving: zero drone. At full throttle, attack mode: straight up aggression (all with no power compromises). Just like a valved system. The Downpipes: When volume is your speed. Turn your SQ5 up to 11 with the AWE SQ5 Non-Resonated Downpipes. These handcrafted T304L stainless steel Non-Resonated Downpipes produce a distinctive, more aggressive sound when coupled with the AWE Touring Edition Exhaust (available separately).
