Full header-back exhaust systems
It seems as if producing full header-back systems with cat/restonator delete is really a select business. So far only Miesterschaft and Kriessieg have done so. In regards to the E92 M3 it looks as if only rear silencers and X pipes with resonators are going to be sold, and the only place to get full non restricted systems is Eisenhaus. My question is should we trust them again? or wait until someone else picks up the slack?
another option is having a straight pipe exhaust custom made. not so sure on the expense of that though.
