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 opened and closed regardless of what mode the car is in.
When compared to other systems on the market and the BMW performance exhaust, the Valvetronic Designs system gives a much more raw and engaging sound experience. Due to the construction methods of the system, the system flows far better than the BMW performance and others. Many systems run a single 3 inch pipe all the way back, and this is not the ideal setup for sound and performance. Splitting into two 2 1/2 inch pipes allows for better flow characteristics and far superior sound!
