Hello,
I picked up my car for brand new 2012 m3 a month ago and just installed Akrapovic slip-on exhaust a 3 weeks ago!
it was 1200km my m3 at that time, and running 2100km now so used only 800km! still have original box and warranty paper and install.
and I didn't use at all over 4rpm. asking price $2800 OBO ,
I'm live in Toronto, location yonge&finch so pick up is available! shipping is available!
If someone interest in, please pm me any questions!
