E46 325i exhaust flange repair kit - help needed re part sourcing, etc.

Recommended Posts

Following my recent MOT on my 2003 325i Touring, my mechanic told me that the exhaust mountings need attention. At the point where the flanges meet (after the manifold cat), one nut has rusted off (leaving just the bolt) and the other has rusted over so it can't be undone when exhaust replacement is needed. He said that there's a flange repair kit for the E46 M3 and showed me a link to a typical product (inserted below). Despite a great deal of searching, I've only been able to locate kits for the M3, and despite several listings saying 'universal', the compatibility chart always comes up the same: 'Won't fit your car.'

Does anyone know of a kit that will fit my car, or failing that, have any tips re drilling out the rusted bolts - which seems to be the only option so far, a job which my mechanic is understandably not looking forward to.

The exhaust isn't blowing - yet, but it's probably on borrowed time now.

Thanks in advance for any help.

A common fault on E46 325i models is failure of the exhaust flanges caused by rust / corrosion of this part. That's why you should always have Gasket rings, Stainless steel bolts etc in your best tool cabinet in order to cut new flanges up, fit and re-weld them. Or you can buy new kit via x8r or other stores.
