APR TT RS 2.5 TFSI RSC Exhaust System
RSC™, Reflective Sound Cancellation, allows for maximum exhaust gas flow while completely eliminating unwanted in-cabin sound resonance known as "drone". RSC™ incorporates innovative technologies developed in conjunction with NASA. With limited use of packing materials and no baffles, RSC™ allows for a completely straight and free-flowing exhaust path throughout the RSC™ mufflers. Reflective Cancellation bounces the undesirable sound waves into each other to attenuate the wave and completely eliminate the low-frequency tones that create drone. Each RSC™ muffler is tuned to eliminate specific, undesirable sound frequencies allowing only the engine's true and desirable exhaust note to be heard and improving performance.
APR's design specifications and manufacturing requirements resulted in a 4" v-band turbo outlet with a smooth transition into a 3" mandrel-bent stainless-steel design. The APR RSC™ Downpipe features a high-flow 200-cell metal matrix catalyst and connects seamlessly with the APR RSC™ or factory catback exhaust system. When connecting to the factory catback exhaust system, the downpipe splits from a 3" design to a dual 2.5" system after the secondary catalysts. Alternatively, when used as a full APR RSC™ Turboback Exhaust System, the downpipe remains as a 3" system and connects directly to the APR RSC™ Catback Exhaust. In either setup, no cutting or welding is necessary as the system is a direct fit and includes all necessary components for connecting to either the factory catback or APR RSC™ Catback.
Each configuration is constructed from low-carbon stainless-steel with high-precision jewelry-grade TIG welding and high-precision CNC MIG-welded components. High-Strength Torca exhaust clamps ensure leak-proof operation through the unrestricted design and a lifetime warranty ensures years of worry-free operation.

The APR TT RS Turboback and Downpipe exhaust system is fully compatible with APR's Stage II ECU Upgrade. Stage II is a free upgrade for existing APR Stage I ECU Customers and is designed to maximize power output from the 2.5 TFSI Engine when coupled with the free flowing exhaust system. With lower exhaust gas temperature and unrestricted exhaust flow, APR's engineers are able to safely extract more power while working within the OEM and Tier 1 Supplier specifications for engine component stress tolerances and performance specifications. Turbocharger lag is reduced resulting in quicker acceleration every time you press the throttle! Click the tabs below to see the gains!
