Exhaust Akrapovic Evolution BMW 1 COUPE M 04-11 - 06-12

The Evolution performance exhaust system, made with Akrapovic specific titanium, includes a silencer, connecting pipes and a resonator to be mounted after the original down-pipes. These connecting pipes have larger diameters and connection flanges in cast titanium. The secondary catalytic converters must be removed, reducing both weight and back pressure, thus increasing exhaust tone and power output. For the ultimate in weight reduction, tuning potential and racing sound, non-catalyst steel pipe options are available. For true enthusiasts, it is possible to mount the Akrapovic audio kit and complete the look with a set of four exclusive titanium or carbon fiber silencers. When installing this product, whether with or without a catalytic converter (which you remember are developed for track use only), you must also remap the ECU to avoid potential "check engine light" warning signals THE PRODUCT DOES NOT MEET THE REQUIREMENTS OF EMISSION COMPLIANCE FOR ROAD OR HIGHWAY USE.
