Unleash the untamed power of your Mustang GT with the MRT Extreme Quad Tip Cat Back exhaust system - an exhilarating upgrade designed to deliver the true essence of Mustang performance. The MRT Extreme line of exhaust offers our most aggressive exhaust sound: an "always on" rumble at idle releases into a frightening roar that screams "take no prisoners." We achieve added performance by maximizing exhaust flow and reducing back pressure: this cat back system includes our h pipe design (over x pipe), which offers a freer, least restrictive, and more direct exhaust path, meaning MORE power and efficiency. This classic H-pipe design also deepens the exhaust note for a smoother tone, producing a captivating exhaust note that's pure muscle car DNA.
We offer the highest quality exhaust systems because each one is specially designed for your vehicle and each one is handmade. Engineered, designed and assembled in the USA and constructed from premium T304 stainless steel, polished SS 4" tips and 3" mandrel bent tubing this exhaust system adds power and a touch of sophistication to your American muscle car. The T304 stainless steel is high quality and corrosion resistant so this is a mod that will last. Black Ops matte finish 4" quad tips are available for an additional fee. This system is engineered for the best sound to match your GT and provides increased performance from increased exhaust flow. The MRT
Extreme Cat Back is the loudest MRT cat-back. The MRT Sport Touring cat-back (
MRT Part # 93U917) has an elevated sound and a bit more drone to Hear (and feel) the power while the MRT Sport Touring cat back with drone management (
MRT Part # 93U916) is the best option for a louder exhaust versus stock with a comfortable driving experience.
MRT aftermarket exhaust systems do not have the AFM or NPP valves increasing performance and flow. This premium MRT Mustang exhaust includes Power Plates to simulate the valves and avoids a check engine light (CEL) from appearing on your dashboard. For more information on these plates, refer to
MRT Part #92G155.
Application: 2018+ Mustang GT Coupe and convertible
