FMIC.Pro electronically controlled cat-back exhaust system for Audi R8 4.2 V8 2008–2012
The FMIC.Pro cat-back exhaust system is designed to improve exhaust flow and give the car a distinctly sportier sound.
The 70 mm (2.75”) pipe diameter and optimized muffler design produce a deep and full sound under load while maintaining good driving comfort during normal driving – especially when the exhaust valves are closed.
The exhaust system is made entirely of SS304 stainless steel, which offers excellent resistance to corrosion and high operating temperatures. CNC-precision-bent pipes ensure uniform geometry and precise fitment to the car's original mounting points. Installation is straightforward and follows a plug & play principle. All weld seams are TIG welded under argon gas protection, ensuring clean, finished, and completely airtight joints as well as excellent durability over long-term use.
CNC-machined, 10 mm thick flanges are used at the connection points. They increase structural rigidity, reduce the risk of deformation caused by temperature fluctuations, and ensure an even seal across the entire mating surface.
The exhaust system features integrated electronically controlled exhaust valves that regulate the path of exhaust gases at the rear of the exhaust system. When the valves are closed, exhaust gases flow through the entire muffler system, keeping the sound subdued and driving comfort high. When the valves are open, exhaust gases bypass the rear muffler, making the exhaust system's sound louder, more direct, and sportier.
Thanks to this solution, the driver can adjust the exhaust system's sound according to driving conditions and personal preferences. The valves are controlled by the included control unit and two remote controls, which allow the operating mode to be switched instantly.
To maximize the performance potential of the FMIC.Pro cat-back exhaust system, it is recommended to combine it with a high-flow downpipe, especially on turbocharged engines.
The exhaust system is designed for use with the car's original exhaust pipe outlets.
