Hello I know that this topic already exists in a different form. But I put it on another reason. And this: How does the Tüv see that I adapt and install a non-vehicle exhaust system under my Jetta 2 VR6 ?? I thought of a Golf 4 R32 exhaust system. Consisting of pots as original. I would then place the VSD of the R32 where the MSD is at the 2er Jetta. Would there be problems with a registration ??? The volume will be as with the R32 so that the registration is possible. ig. Or does another § stand in my way??? Achso Krummer trouser tube and Kat Stay original of VR6
