Akrapovic Cat-Back Exhaust System For BMW 1 Series M

Description

Building on the modular theme, the Akrapovic BMW 1M Evolution Exhaust System includes the Slip-On System and then adds titanium link pipes to it with resonators that run from the stock downpipe back. These link pipes feature larger-than-stock-diameter tubing and cast titanium flanges that are made at an in-house foundry for a perfect fit. In addition, the secondary catalysts are removed, further decreasing backpressure and weight while at the same time deepening the exhaust tone and increasing power output. No ECU reprogramming is required in this configuration. The check engine light will not be triggered. For the ultimate in weight reduction, tuning potential, and racing sound, Akrapovic offers stainless steel, Race downpipes. When used in conjunction with the Evolution System, this is virtually the same setup used on the 1M Moto GP Safety Car. The high-flow downpipes do require ECU reprogramming to eliminate the check engine light and for peak power output. They are only for the dedicated track day car or hardcore enthusiasts. To cap off any of the systems, Akrapovic offers either carbon fiber or titanium exhaust tips. Both versions feature a spherical mounting system to allow for perfect alignment of all four tips. The carbon fiber tips are constructed at their in-house production facility using “prepreg” cloth that is vacuum-bagged and autoclaved. The result is an attractive yet extremely durable part.
