downpipes

I just pulled the trigger an ordered some Mad downpipes. Do i need to order anything else along with the downpipes? new gaskets or clamps? or should i be good with the existing stuff from my 40k mile m5?

Probably new gaskets and clamps. It’s not strictly mandatory if your OEM ones are in great shape at 40k and they fit, but most guys replace them to avoid leaks later. Also, you’ll definitely want an ECU tune to get the most out of your new setup.

Heat wrap or get em ceramic coated.
