Hey guys, I'm thinking of installing the 435i dual exhaust into my 328i
Went to muffler shop to get a quote they said I can not do it on my stock bumper because there is not enough clearance on the driver side. There is a heat shield and it looks like a panel that needs to be removed. Anyone know if there is even anything inside there? Since it looks like swapping to the m sport bumper fixes the problem.
Thanks
