Constructed from high-grade austenitic stainless steel, each link pipe contains a 200 cpsi catalytic converter and the set weighs over 43% less than the stock equivalent. A tuned resonator – specially developed for the engine – provides a unique deep, rich, and sporty sound with no drone. Designed for use with the Akrapovi? Slip-On Line (Titanium) exhaust system and for use on racetracks and closed courses only, remapping is mandatory when installing this product.
