Frequently Asked Questions
What is the CORSA 14397GNM?The CORSA 14397GNM is a 3.0-inch Sport cat-back exhaust system for the 2017-2020 Ford F-150 EcoBoost Raptor 3.5L Turbo, featuring a single 5-inch gunmetal PVD Pro-Series tip and CORSA's patented RSC technology for aggressive sound without highway drone.
What does GNM stand for in CORSA part numbers?GNM designates the Gunmetal PVD-coated tip finish. It offers the same exhaust system performance as the base 14397 but with a dark metallic tip finish suited for off-road and blacked-out vehicle aesthetics.
Is the gunmetal tip durable for off-road use?Yes. The gunmetal PVD coating on the T304 stainless steel tip is designed to withstand the heat, debris, and environmental exposure of off-road driving without flaking or corroding under normal use conditions.
Will this fit both the SuperCrew and Super Cab Raptor?Yes. The CORSA 14397GNM is specifically engineered to fit both the Super Cab and SuperCrew Cab configurations of the 2017-2020 Ford F-150 Raptor 3.5L EcoBoost Turbo.
What is the sound difference between 14397 and 14397GNM?There is no sound difference. Both are tuned identically to the Sport sound level with RSC technology. The only difference between the 14397 and 14397GNM is the exhaust tip finish.
Does the 14397GNM require a tune or re-flash?No. The CORSA 14397GNM is a direct bolt-on cat-back replacement that does not require any engine tune, ECU re-flash, or modifications to the factory exhaust sensors or emissions equipment.
Is there a warranty on the 14397GNM?Yes. CORSA Performance provides a limited lifetime warranty on all exhaust systems including the 14397GNM when purchased from an authorized dealer and used under normal on-road conditions.
How long does installation take?Most installations take 1 to 2 hours with basic hand tools. No cutting, welding, or special equipment is required. The system uses factory mounting points and clamps directly.
