Default Changing back boxes - part numbers for nuts, bolts and gasket?

When I swap my box I want to be prepared.

Does anyone have a list of the bits the gathered before doing the swap themselves?

Cheers

The clamp bolts sometimes shear, that’s all I bought. The hanger bolts etc in would just reuse.

I think the clamps were about £15 each from bmw

Do you need to use exhaust paste between the connecting pipes and x-pipe before clamping up?

I didn't when I did mine, as it didn't look like there was any there in the first place, and the mechanical connection seems firm enough, but I've always wondered.

I did and would do so on any exhausts joins but I dare say it’ll be fine without.

If it's an e9x, be prepared for the ground cables to snap too. They're attached either side of the backbox. Cost about £40 each to replace.

Mine both corroded off when i had mine removed. Didn't replace them and *touch wood*, nothing untoward has happened yet...

And if you have new hangers it will save you time, took me half hour to remove the left on off my old backbox, right pain in the ass.
