HP35 Slip-on Mufflers

The Rinehart Racing HP35 Slip-on mufflers are engineered to provide high performance and distinctive styling for 2018 and later Harley Softail models, including the Softail Slim, Low Rider, Street Bob, Breakout, and Fat Boy. Constructed with USA-made materials and featuring the unique DBX style performance catalyst baffle, the 3.5-inch mufflers are built to offer a significant boost in horsepower and torque. However, tuning is recommended for optimal performance, though not strictly required. It's important to note that the replacement of OEM gaskets is necessary for installation, and these are not included with the mufflers. This exhaust system is catalyst equipped and meets 49-state emissions compliance. It is explicitly not legal for sale or use in California on any pollution-controlled motor vehicle. Furthermore, these slip-ons do not fit 2018-Later Fat Bob models.
