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.
The B5 S4 in the video has a full APR RSC Exhaust System with an APR Stage III K04 turbocharger System.

USP Motorsports Audi B5 S4 Tial 605 Twin Turbo Kit
TiAL Sport S605 turbo Kit - 2.7T:
We built and tuned this 500+ wheel horsepower beast and had to
find out what it can do.
Needless to say, the car was very impressive. A very smooth power band and
peak Boost is achieved quickly. The
car has a TiAL 605 turbo kit, mated with
every supporting component the car can handle. All of this was done on a
completely STOCK motor! Check it out!
The 600 HP APR Stage 3 Audi TTRS - /TUNED
Alabama is the last place you'd expect to find one of the world's largest
tuner companies for German cars, but here, at this facility, APR provides
hardware and software to thousands of Audi and VW customers every month.
Matt helps them with some development testing by providing opinions on
their new Stage 3 package for the Audi TTRS, producing 560 horsepower at the wheels in
a car based on the VW Golf!

ECS Tuning: APR 3.0 TFSI Stage 2+ Supercharger Pulley Upgrade Kit DIY
Available at: http://www.ecstuning.com/ES2214953/?utm_source=Youtube
APR likes to be pioneers in the automotive world and that shows with this
new Supercharger Pulley Upgrade, a world
first for the 3.0 TFSI motor. This part requires you to have the Stage 1
upgrade before you can upgrade to the pulley with Stage 2. What's the
reason for this you might be asking?
Without recalibrating the ECU found in your vehicle, pulley upgrades offer
no advantage, as the Supercharger will
simply bypass Boost pressure. Yet,
with the upgrade, they are able to develop new hardware and calibrate the
ECU to work properly as if it was intended by the factory.
When you upgrade the ECU, many expect a massive increase in torque, but
that simply isn't the case with these new supercharged motors. The ECU
upgrade offers up more power, but if you want insane amounts of torque,
this new Supercharger Pulley Upgrade is
for you. The gain in torque is felt immediately, but the results are
present from beginning to end adding up to 80ft-lbs and 108 horsepower at all four

With factory like smoothness and drivability APR's ECU / Pulley Upgrade
will fill the void in an otherwise excellent car.

500 hp Audi S4 quattro vs 12"+ of fresh snow! Unstoppable...
Last night we enjoyed a great winter storm, well over 12" (30 cm) at my
house. I wanted to see if my lowered Audi S4 on Dunlop Wintersport 4D snow
tires was up to the task going through such deep snow.

APR MK7 GTI ECU Upgrade - Motorsport Testing
The APR Stage I ECU Upgrade is designed to work without requiring other
changes to the vehicle's hardware. With the ECU Upgrade alone, APR's
Calibration Experts measured higher peak figures of 381 ft-lbs of torque
and 316 horsepower
with 93 AKI octane fuel. Large gains were seen throughout the power band,
including an additional 114 ft-lbs of torque and 87 horsepower. Even higher
figures were acheived using 100 AKI octane race fuel. The increase in power
directly translates to an exceptionally quicker vehicle. Using advanced GPS
measuring devices and the local IHRA certified drag strip, APR's engineers
conducted several acceleration tests. During the quarter mile sprint, the
APR Stage I equipped vehicle crossed the finish line 1.06 seconds quicker,
with an exit speed 13.3 MPH faster!
APR's ECU upgrade is the best power per dollar modification for the new 2.0
TSI engine and takes the vehicle's performance to similar levels typically
reserved for higher output, sporty models, without pushing the limits. With
factory-like smoothness and drivability, APR's ECU upgrade will fill the
void in an otherwise excellent vehicle.
