For the 2018 model year, BMW has doped the gauntlet with the release of the AWD Twin Turbo V8 powered M5. Being the most powerful M5 ever made, its only fitting that Remus offers its most aggressive sounding exhaust for it as well.
The Remus Race Exhaust system still utilize the factory valves in an attempt to quell the power and sound of that Bi-Turbo V8. Helmholtz resonators are used for each bank of cylinders when valves are closed to keep things more civil. But when your ready to wake the dead, those valves open up offering straight-pipe levels of sound and fury!
