Complement the seductive growl of your Corvette C8 with the MRT sport touring, quad-tip cat-back exhaust system. MRT designed this cat-back system sound to be 10-15% more aggressive than the sport model of the factory system. It's a 3" pipe straight through design providing maximum performance and no backpressure in the exhaust system which means actual horsepower gains without a tune and a performance sound without being obnoxious.
At idle and start-up the C8 definitely has a nice, deep full exhaust presence and note that is not overwhelming. As you transition into the wide-open throttle, the system is full of song and people are going to know you're coming. It's a gorgeous sounding system that definitely says look at me when you want it and quiet when you don't.
MRT's focus on excellence goes into every detail of the construction and design of this premium cat-back exhaust system. The cat-back is handcrafted with T304 stainless steel construction, 3" mandrel-bent tube for maximum airflow and sound performance. Quad 4" polished T304 stainless tips are standard with a stealthy "black ops" black matte high-temperature finish also available.
MRT AFM plates are included in the kit to prevent a check engine light on 2020 models and not require a tune when you install an aftermarket exhaust system.
2020 and 2021 Corvette C8 6.2L V8 engine.
Other Corvette models.
It has been brought to our attention that 2021 Models may require a tune or aftermarket solution in order for the secondary exhaust valves to not throw a check engine light. If you are willing to send us your secondary exhaust valve actuators, we will engineer a plate for them to operate without setting off the CEL. Just give us a call at the number below if you are interested in helping us do this.
