Let me know. I have been looking everywhere for a 2006 M5 can.

Not too sure on the M5 stuff.

Try one of the distributors- like

I had an MBRP can on my old M7-    and with 3000km's  it was getting louder and louder with every ride-   it was packing out.

My girlfriend runs a ceramic coated Speedwerx pipe/can combo on her M7-   she likes it.
D&D also makes good stuff.    Are you looking to save weight or more looking for some braaaap sounds? 

How's the riding wayyyy the fukk up there?   AK EH!  Got any pics?

I was more braaaap of course haha. but ya its pretty fuckin good here. i can give you pics in a few days i dont have enough time right now. but im gonna check out those sites thanks a lot.
