BMW 1M Akrapovic Slip-On Titanium Exhaust system
Akra-1MSO
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 TÃœV 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.
BMW 1M Akrapovic Evolution Titanium Exhaust system
Akra-Evo1m
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.
