Product Details Technical Specs Installation Instructions

The MRT Street Race Cat Back Exhaust System for the C8 Corvette is the ultimate track car exhaust system and the most aggressive in terms of sound. It's your best choice for performance sound that you can legally drive on highways and city streets. While the Next-Gen Corvette is already a head-turning car, we know some owners want to make the high-performance leap while hearkening back to Corvette's muscle car roots. You'll Hear the Different and Feel the Performance the moment you first turn the key after installation.

This C8 Corvette exhaust 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 gives your C8 Corvette a 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 you're coming under vehicle acceleration.

Street Performance Corvette Exhaust

When you demand a growling, forceful exhaust tone at all times, our Version 1/Street Race series will provide it so you Get Noticed. 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 three-inch tubing. The system comes standard with polished four-inch quad tips and a "Black Ops" ceramic matte finish to match the sporty sound.

The MRT Street Race Cat Back System is our loudest C8 exhaust with minimal very comfortable drone presence. The enhanced exhaust flow increases horsepower from the LT2 engine so you go as fast as you sound. MRT's Street Race Cat Back also provides 32 pounds of weight savings compared to the stock C8 exhaust system, helping you get off the line in a hurry.

This MRT aftermarket exhaust system does not have the AFM and NPP valve simulators so each premium C8 exhaust includes a simple plug-and-play exhaust module to simulate the valves and avoid a check engine light (CEL) from appearing on your dashboard. Although you can install the Street Race C8 Stingray Cat Back yourself, it is more cumbersome than other MRT systems because you need to remove and reinstall the rear bumper. As such, we recommend professional installation.

More C8 Exhaust Systems

MRT also designed a Sport Touring cat back exhaust for your C8 Corvette. This system is for someone who wants 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 the C8 Corvette MRT Sport Touring Cat Back #91S220 for more information and a sound clip of the system. All MRT exhaust systems are backed by a limited lifetime warranty and our superior customer support.

Application: 2020+ C8 Corvette, 6.2L V8 engine

Hear the Difference

  • How does it sound? The MRT Street Race Cat back gives an aggressive, Get Noticed exhaust tone that is always present.
  • Is there drone or resonance? The drone is noticeable yet very comfortable for all driving conditions
  • What if I step on it? Wide-open throttle brings out a livelier attitude with more exhaust sound, more bite and a deeper growl.

MRT designed the Street Race Cat Back system as a direct fit for your C8 Corvette. Professional installation is recommended with an estimated 5-6 hour installation process. If you're located close to Plymouth, Michigan, one of MRT's mechanics will be happy to install the C8 Street Race Cat Back Exhaust for you. Call MRT at 734-455-5807 to make an appointment.

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.
