Akrapovic - Evolution Titanium Exhaust System - BMW E82 1M

In a way, the BMW 1 Series M Coupé is a throwback to the past. This twin turbo, 335+ horsepower coupe reminds many BMW diehards of the early M cars, in which light weight, small size, and agile handling were the only things that counted. Do we dare to improve on such a focused, purpose-built machine? Yes, we do. At Akrapovič we’ve developed several different configurations to suit all tuning applications. The basis of all the configurations is our Titanium* Slip-On system. Utilizing a single muffler arrangement, the Slip-On is designed to be modular. In its basic mode, all exhaust gases flow through the main body of the muffler, giving you a deeper rumble of an exhaust note compared to stock without any drone. In Europe this system meets TÜV standards for noise. However, the muffler system is built in such a way that by replacing a blocking plate with our Wireless Kit valve system the driver is able to noticeably increase the volume of the exhaust at the press of a button. Once activated, the majority of the exhaust gases route through the muffler bypass outlets. Building on the modular theme, our Evolution System includes the Slip-On 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 our 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. The Wireless Kit mentioned in the Slip-On description can also be used with the Evolution System. For the ultimate in weight reduction, tuning potential, and racing sound, we offer stainless steel, catless 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, we offer 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 our in-house production facility using “prepreg” cloth that is vacuum-bagged and autoclaved. The result is an attractive yet extremely durable part.
