Big Gun 07-19 Honda CRF 150R/Expert EVO R Series Full System Exhaust

The EVO R series is designed to save weight, add noticeable performance gains, and improve sound compared to stock exhaust systems. It features a hard anodized oval-shaped aluminum muffler, TIG welded reinforced muffler brackets, a 304 stainless steel mid pipe/head pipe, and a red powder-coated stainless steel end tip. It's lighter than stock and offers significant horsepower and torque gains. The sleek design provides maximum clearance, and a removable screen-type spark arrestor is included. Handmade in the USA with a 1-year limited manufacturer's warranty. Proper tuning (jetting for carbureted vehicles, fuel controller/programmer for fuel-injected vehicles) is required to maintain the warranty and prevent the motor from running lean. Muffler repacking every 15-20 hours of ride/drive time is also required.
