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. The exhaust system also fits on SP and SP2 model. If passenger footrests are removed optional carbon fibre muffler bracket is needed (as shown on the product image).
