Looking into getting a backbox and center section for E46 m3. Has anyone any experience with Scorpion or Schmiedmann exhausts?
I understand scorpion would be considered budget, but from what I can gather, it is made in UK and to decent quality. Cant really find anything on Schmiedmann at all, no sounds clips, no forum posts.
I know there are others like miltek, eisenmann but not sure if they sound that much better for the fee they commanding, 1.5k just for the backbox.
