This exhaust fits cars with OEM M-Tech rear-bumber. Only the Diffusor needs to be replaced (diffusor is not included). You can just use the original BMW M340i diffusor. This one has the perfectly fitting outlets for this quad-tailpipe-exhaust and fits into the bumper without any changes. Order the diffusor directly from BMW (part number: 51128069391). The OEM exhaust then can be replaced 1:1.

Of course with TUV approval ( EC approval / ECE approval / EG-ABE ).

This is a complete exhaust system with flap controll - all parts, mountings and clamps are supplied by us:

The exhaust is equipped with two exhaust valves / flaps and is connected to the OEM flap control. So flaps can be opened though the OEM driving profile buttons and can be opened in Sports or sports+ mode. The valve bypasses the whole rear silencer so the sound with opened flaps will be very aggressive / sporty and the sound can be controlled by the driver.
