Here’s the Ericsson M480 full titanium system for the E92 M3. Gotta love the double barrel design which is going to be my base idea for my own stainless exhaust system. Tough the E34 only allows for a single side. I might be getting a custom fuel tank in the future to allow for twins on either side. There are also a couple of other exhaust system in the gallery, namely the Supersprint system for the E60 M5.
