Akrapovic Titanium Evolution Short Link Pipe Set For G80 BMW M3 / G82 BMW M4

Constructed from high-grade titanium, this lighter-than-stock link pipe features a resonator in the middle part. Available for the United States only, the link pipe is shorter, allowing the stock catalytic converters to remain on the car. Combined with a Slip-On Line (Titanium) and delivering a deep, rich, and sporty sound without drone, it totally embraces the pure turbocharged inline six-cylinder sound. Remapping is mandatory. This product is meant for racetrack use and closed courses only.
