Styled and designed directly from the WorldSBK exhaust, this muffler is constructed from race-proven materials using lightweight titanium and finished with a hand-made carbon-fibre heatshield. This entry-level introduction to exhaust tuning already provides that unique Akrapovi? sound. The muffler valve housing is made in Akrapovi?’s in-house titanium foundry. It has a simple plug-and-play installation, and is fully EC- and ECE-compliant. Optional headers are available for enhanced power. If used with optional headers, remapping is required. For perfect performance, throttle response, and durability, special mapping developed by Akrapovi? R&D in collaboration with our partner Rapid Bike by Dimsport is recommended. Please visit https://www.dimsport.us/en/rapid-bike/akrapovic/, where you can download the mapping. If passenger footrests are not installed carbon fibre muffler bracket is mandatory (as shown on the product image).
