Borla put double their usual R&D time into developing these mufflers specifically for the rotary engine. They thickened up the stainless to avoid burnout and used special packing to handle the additional oil present in a rotary exhaust. Borla then took the time to tune the sound perfectly in the high RPM range. These are the best rotary specific mufflers on the market.

Case Size: 16″ long x 6.25″ round.┬áPlease check fitment using the specs before ordering.
