- optional Wireless Kit for Exhaust Valves (P-HF597): EUR 590 ("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.")
