Valvetronic F87 M2 N55 Exhaust System

Welcome to the F87 M2 N55 valved exhaust system. This system was designed from the ground up to give you max sound out of the N55 but of course, allow you to close the system for comfortable daily driving as you please. Constructed out of T304 stainless steel the Valvetronic F87 M2 exhaust connects to any downpipe and initially runs 3 inches in diameter until splitting in favor of two 2.5 inch mandrel bent pipes all the way back to a set of beautiful quad tips. Splitting into 2 pipes right after the downpipe helps accelerate exhaust gases out of the system for more power and exceptional sound. This system features vacuum-actuated exhaust valves for a fast close and proven longevity. The system operates on a stand-alone controller module and can be open and closed regardless of what mode the car is in.
