This full system exhaust has been cleared by the California Air Resources Board (CARB) and has met the requirements of the Environmental Protection Agency (EPA) as legal for sale and installation in all 50 states.

The new Slimline Catalyst Duals exhaust system features a proprietary Power Flow catalyst engineered to outperform even “open” catalyst-free systems. The results observed in independent dynamometer testing show significant increases in power and torque compared to stock exhausts and other emissions-compliant systems currently on the market.

Other design features promise to make this latest rendition of Rinehart’s classic exhaust system a must-have for Harley Touring motorcycle owners. The unique design moves the catalytic converter away from both rider and passenger legs and feet, providing a cooler and more enjoyable ride. The system also features 12mm and 18mm O2 ports, optimally placed for dyno tuning and proper measurement of exhaust gas concentration from the port, allowing the engine to perform efficiently.

The Slimline Catalyst Duals are sold in a complete system with a choice of Rinehart 4” Slip-On mufflers or Rinehart 4.5” MotoPro45 Slip-On mufflers. The system is available in chrome or black, with chrome or black end caps. In addition to being legal for sale and installation in all 50 states, the Slimline Catalyst Duals are backed by Rinehart’s limited lifetime warranty.
