2020+ C8 Corvette MRT Street Race Cat-back Exhaust

The MRT Street Race cat-back exhaust system for the C8 Corvette is the ultimate track car exhaust system and most aggressive in terms of sound. It's definitely your best choice for street performance sound. This system is a straight-through muffler delete design that is all about providing maximum flow and maximum performance that matches the performance sound and aggressive performance look of the C8 styling. This MRT cat-back system provides a definite, pleasant exhaust performance presence throughout the drive cycle and even provides a few burbles and crackles as you lift off the gas and between transmission shifts. It's an "I'm ready to roll" exhaust sound that clearly says I'm coming under vehicle acceleration.

MRT designed the Street Race C8 cat-back system to give you all the performance an exhaust system can give and is handcrafted in T304 stainless steel and mandrel bent 3" tube. The system comes standard with polished 4" quad tips and a black ops ceramic matte finish to match the sporty sound. This MRT Street Race cat-back system is our loudest C8 exhaust with minimal very comfortable drone presence.

All hardware required for installation is included in the kit AND we include the MRT AFM power plate to simulate valve function and prevent a check engine light or require a tune.

Application: 2020 and 2021 Corvette C8 6.2L V8 engine
Doesn't Fit: 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 new 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.
