Akrapovič BMW 1M (E82) Evolution Titanium Exhaust System
Our Evolution performance exhaust system, constructed from our proprietary titanium, includes a muffler, link pipes, and resonators that extend from the stock downpipes to the rear. These link pipes feature larger-than-stock-diameter tubing and cast titanium flanges, and the removal of the secondary catalytic converters further reduces back pressure and weight. This design deepens the exhaust tone and increases power output. For those seeking the ultimate in weight reduction, tuning potential, and an aggressive racing sound, we offer optional stainless steel catless downpipes—ideal for hardcore enthusiasts. For adjustable sound control, the optional Akrapovič Sound Kit is available. Complete the look with a set of four exquisite tailpipes in titanium or carbon fibre.
Important Installation Note: When installing Akrapovič aftermarket optional downpipes with sports catalytic converters or without catalytic converters—designed for use on closed tracks only—remapping the ECU is mandatory. Additionally, for any Akrapovič aftermarket exhaust system developed for closed track use, we recommend remapping the ECU to prevent potential “check engine light” warning signals.
IMPORTANT: THIS PRODUCT DOES NOT MEET EMISSION COMPLIANCE REQUIREMENTS FOR STREET OR HIGHWAY USE.
