Engineered Performance for Audi, VW, Porsche & Skoda

APR is pleased to present our first RSC™ Exhaust System for the Audi marque in the new 3.0T B8 S4 Model Years 2010+.

Reflective Sound Cancellation allows for maximum exhaust gas flow while completely eliminating in cabin sound resonance (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 through 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 desirable exhaust notes to be heard and improving performance.

To continue with even further refinement and power potential out of the 3.0T, new features never before offered by APR Exhaust Systems are introduced to the B8 S4 application in addition to the patented RSC™ Technology:

Unique Exhaust Tip Options

APR's RSC™ Performance Exhaust for the B8 S4 introduces modular tip design that allows the end user to specify an initial tip color of either Stainless Steel or Diamond Black and other tips can be ordered separately and changed at the owner's pleasure. Be on the lookout for special edition, limited run tip options in the future to make your S4 even more exclusive and individual to your tastes. Installation and removal of exhaust tips can be accomplished easily with only basic hand tools.

Integrated Elliptical Crossover Assembly (X-pipe)

Normally Aspirated engines and Supercharged engines still rely on proper exhaust tuning to promote the optimal flow velocity of exhaust gasses leaving the exhaust ports. APR introduces a unique and proprietary X-pipe design that was developed through multiple reiterations to perfectly match the pulse of each cylinder in the 3.0T to provide optimal exhaust flow. Often times, exhaust manufacturers will incorporate X-pipes into all Normally Aspirated or Supercharged applications generically without realizing that the sizing and shape of the ports in the X-pipe require specific tuning to each engine application. APR's Engineering Team has discovered a trade secret exclusive to APR's RSC™ Exhaust System that promotes maximum velocity of exhaust gasses by way of the X-pipe to ensure your APR RSC™ Exhaust System will compliment your future modification choices at even the highest horsepower and torque possible.

Full Catback Component Overview

The OEM exhaust system consists of Headers, Catalytic Converters, Resonated Downpipes, a Center Resonator, Rear Mufflers and Exhaust Tips. The APR RSC™ Performance Exhaust System is a Full Catback Exhaust System as it replaces the OEM Resonated Downpipes, Center Resonator, Rear Mufflers and Exhaust Tips. Illustrated below is the OEM exhaust system with the components replaced by the APR RSC™ Performance Exhaust System in bold.
