MagnaFlow’s xMOD Series exhaust system is here for the 2020-2021 Chevrolet C8 Corvette, designed to bring you the best sound, appearance, and performance experience. Transform the sound of your C8 from mild to wild with 4 different configurations using the interchangeable Muffler Modules or xTreme Deletes while maintaining full functionality of the factory Bi-modal technology. The option of race-inspired 4.5in Round Tips in either Bright Silver or Black Chrome gives you the flexibility of customizing for the look that best suits your car. Ready for any extreme you can throw at it thanks to carefully engineered heat shielding, every aspect of the xMOD Series system is designed to make your C8 sound and perform like the supercar it is.


MagnaFlow’s extensive research and development process for the C8 Corvette led our engineers to create a specific set of a valves designed to interface seamlessly with C8’s OEM actuators valves to ensure proper functionality and reliability of the C8 under all driving conditions. Testing on both our in-house dyno and a specially designed valve test bench gave us the opportunity to develop this technology in a controlled environment for long-term reliability. Real world testing included logging miles on multiple vehicles in a variety of different operating conditions on the road and track. xMOD for the C8 delivers dyno-proven performance, weight savings, and the quality you expect from a MagnaFlow offering.


The multi-metal construction of the new xMOD Series exhaust for the C8 Corvette is highlighted by the use of 304 Stainless Steel in the tubing, brackets, tips, valves and flanges of the system. This material choice enhances the appearance of the system while mitigating surface oxidation to ensure your MagnaFlow exhaust will retain an attractive appearance for years to come.
