Cat Back CourseTronic BMW G8x M3 / M4

Beauty is not just in appearance; sound plays a role too! True, the G80 has a grille that may seem a bit odd, but without a doubt, it is one of the strongest new M cars. However, its sound from the factory does not meet expectations. This is where KORSATRONIC comes in – we modify the original exhaust and make its sound worthy of the M level.

With a mid-pipe measuring 3.5 inches in equal length design, you'll experience an exciting and smooth sound without having to change the rear part of your original exhaust. It fits on the original downpipes or even open front pipes if you want to upgrade further. Don't worry about the engine light; it won't turn on or cause you any issues. You can install any axle-back exhaust from any other company without problems.

Want to enhance the sound even more? You can add our axle-back or a valve control unit to control the sound with a single button, allowing you to adjust it as you like. The system is made from high-quality T304 stainless steel, and the same design as our well-known quad muffler chambers, meaning a sound that satisfies you in every setting. The pipes run at a size of 2.75 inches from start to finish, and everything is designed for the best flow, sound power, and torque.

And the best part, the tips are double-layered, giving a luxurious look and a final touch to the car.

Don't settle for less and your sound is ordinary; with KORSATRONIC, you'll get a completely different audio experience for the G80. Our quality is unmatched, especially with the new system made from original Grade 5 titanium. Beware of cheap systems; ours is different in material quality and manufacturing.
