Cat-back from KORSATRONIC BMW G20/G22 M340i/M440i

🔥 Welcome to the ultimate sound experience for BMW M340i and M440i cars 🔥

At Koursatronik, we don't do things halfway... Our goal is always to provide a crazy audio experience for performance enthusiasts, and that's why we developed this system specifically for G20 and G22 cars.
We used the largest possible pipe size to give you the sound in the strongest and clearest form, without filtering or smoothing!

The front end of the system measures 3.5 inches, and after the Y-pipe, the system continues with double pipes measuring 3 inches, all leading to the luxurious Koursatronik exhaust tips.

🔊 When do you open the valves?
The sound becomes insane:
– The turbo sound whistles
– Popping on shifts
– And an aggressive sound from 0 RPM to the redline

But when you close the valves?
The car returns quiet as if you are just driving daily, without any disturbance.
Imagine the difference of more than 25 decibels between the valve open and closed!
It means fun without any compromises 👌

✅ Features of the exhaust system with valves:

• Made of T304 stainless steel

• 3.5-inch mid-pipe for maximum sound and flow
