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 Corvette exhaust system is designed in an H-pipe configuration for minimized back pressure flow and a deeper sounding exhaust note. This MRT cat-back system gives your C8 Corvette 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 also designed a sport touring cat-back system for your C8 Corvette. This system is for someone who want to control the exhaust loudness with the throttle input giving an all-time sporty sound that is called to action with full throttle. Check out MRT Part #91S220 for more information and a sound clip of the system.

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.

To avoid a Check Engine Light (CEL) from displaying after installation of your aftermarket exhaust, MRT recommends this simple Exhaust module plug and play solution: MRT Part #91X016. Simply choose this available option with your C8 purchase.

Scott and his team at MRT took great care of my car and the videos don’t do it justice my c8 sounds amazing. It has a deep sound that goes with the look of the car and makes the driving experience that much better. Scott was great to work with and answered all of my questions. The turn around time was exceptional. If you have a C8 I highly recommend going with MRT you won’t be disappointed. I have joined the team and feel they will be there for me even years down the road. Thank you again To Scott and the MRT Performance team. Great work and customer service.
