Stasis Engineering Exhaust System Audi R8 4.2L V8 08+
The STaSIS R8 V8 4.2L Exhaust System replaces the OEM muffler assembly located behind factory V-band connection. The system was designed to specifically fit the following model of car:
Model: R8
Engine: V8 4.2L FSI
Transmission: 6MT or R-Tronic
Drive Train: Quattro
Appl. Years :2008 +
This system utilizes the OEM V-band connection just behind the engine. This allows for ease of installation and provides for a proper interface using a custom designed flange to mate with the OEM flange.
All OEM heat shields are retained to ensure no additional thermal stress is introduced into the vehicle’s structural and cosmetic components.
The STaSIS exhaust system is a direct bolt-in replacement, no welding or fabrication is required. All pipes on the STaSIS exhaust system are made of T-304 Stainless Steel and precisely shaped with a CNC mandrel bender to insure an easy and direct bolt-in replacement. All mounting and support plates are precisely manufactured on a CNC laser cutting table. All welds are back gassed using the TIG method for cleanliness, precision and strength. The exhaust is mounted with the existing OEM exhaust hangers.
The single muffler setup used on the OEM system is replaced with a dual muffler design incorporating a "X" style crossover. This allows a small portion of the exhaust pulses from opposing cylinder banks to cross over and create a pressure depression for the next pulse coming through the exhaust. This effect helps create power by reducing back pressure pulses behind the engine to negative levels.
The STaSIS mufflers incorporates reflective (active) and passive technologies to optimize sound and performance. The round muffler chamber has been extensively developed and tested to achieve the desired overall exhaust tone while minimizing exhaust back pressure to the engine. The STaSIS muffler design gives an exhaust note that is noticeably deeper and stronger at all throttle applications while maintaining a tone that is not intrusive or "droning" at normal everyday driving speeds.
The tail pipes extend into the factory exhaust tips mounted in the rear bumper cover and require no bumper or tip modifications.
Exhaust back pressure was minimized over the stock application. This allows the engine to "breathe" easier resulting in more horsepower. Reprogramming of the ECU in conjunction with the exhaust installation will give a bigger increase in horsepower over the stock exhaust due to the better flow characteristics.
Testing was performed at our facility here at Infineon Raceway, surrounding country roads in Sonoma, and the city streets of San Francisco. Stainless Steel components are designed and proven to perform in corrosive environments (salted roads and ocean-side communities).
