APR Sound tests for the B8 A4 2.0 TFSI exhaust systems.
The vehicle in this video is a 2010 B8 A4 2.0 TFSI. It's a tiptronic and has quattro.
The vehicle is fitted with APR software and two different APR Exhaust Systems.
First, the APR Quad Tip, Dual Exit Catback Exhaust System. This exhaust system extends from the OEM DP out the rear of the car on both sides. We apologize for the unpainted bumper. We simply fitted the quad tip bumper for the video.
The Second Exhaust system is the APR Dual Tip, Single Exit Catback Exhaust System. This exhaust system extends from the OEM DP out the rear of the car on one side.
APR Also offers both systems in a true, full; turboback exhaust system complete with high flow catalytic converter and resonated Race DP. More videos of these systems to follow!
Reflective Sound Cancellation allows for maximum exhaust gas flow while completely eliminating in cabin sound resonance (drone). 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.
