The Akrapovic Optional Stainless Steel Header Set E-H7R1 and the Titanium Silencer S-H7SO4-HRTBL can be combined to upgrade to a full system. Created from superior quality stainless steel, the set offers more torque, power, and reduced weight for an enhanced riding experience. All necessary components and comprehensive instructions for installation are included. No fuel tuning or ECU tuning is necessary, and no port gaskets are required. Once installed, performance improvements can be felt along with an eye-catching aesthetic and the signature Akrapovic racing sound. This product does not conform to road or highway emission standards, and is therefore only suitable for off-road, closed-course use.
