Tubi Style Audi R8 Muffler (4.2 V8, no valves)

This non-valved exhaust system was specifically designed to unlock power hidden in the 4.2L engine and produce a much more aggressive and characteristic exhaust sound. Together with its unique single chamber design, the valveless design relieves back pressure during all driving conditions resulting in gains of 15-20 peak horsepower.
