Well engine and exhaust DO go together. While an axle back will never be the reason for a voided warranty, cats are a different story. Cats dramatically reduce the back pressure and could EASILY be used to deny engine work.
He told me theyve gone to court numerous times and at the wnd of the day BMW has the best lawyers and will basicaly always win; all they have to say is our car was designed to run on stock back pressure.

Ps: BMW could report anyone who tampers with emissions equipment and its a 5 thousand dollar fine...
Also, according to the Clean Air Act from the EPA, the fine is $2,500 and there are many conditions where it is in fact, legal.
