Magnaflow’s Pro Series Diesel Performance Exhaust (#17908) kit is designed to boost horsepower and torque — as well as an improved, tougher sounding exhaust note — for the GM Duramax 6.6-liter diesel engine. The 4-inch single exhaust pipe, which is mandrel-bent and welded, exits on the passenger side of the vehicle and has a particulate filter and intercooled tip. Performance gains are based on the company’s dynamometer testing.
MSRP: $563.75
