In the process of removing my stick DP to go CTS catless. Went to remove the v band and the nut on the backside is spinning. The way the clamp is shaped I can’t get a wrench or pliers onto the backside of it to hold it. The only thing I can think to do is cut the clamp off but I can’t find a replacement anywhere online. Plenty of options for N55,N54 and even B48. But I can’t find the B58 anywhere.
Anyone know where to get one? BMW wants to sell it with the factory downpipe... over $1000.

Thanks!

Cut the bolt, not the clamp. Then get a new one from the hardware store.

Super common problem. I had the same experience. Weehe is right, Dremel the bolt. It will suck. It will take forever. But it's the least shitty option.

poor design of the V band, very un german like!

Happened to me as well. Had to torch the bolt and run to the hardware store.

Part number 18328612537, My first google search found it instock at ECStuning. But like others said, cut bolt and find a replacement bolt

I ended up being able to spin the v band so the bolt was much more accessible. I cut it in the middle and put a new bolt in. Downpipe is in, stage 2 flashed and the car hauls! Thanks for the advice guys 👍🏻

This, we had to cut mine and just get a new bolt.

Take a vice grip to the clamp where the nut is so that the clamp grabs the nut more. Make sure the flats of the nut are up and down before you squeeze the clamp.
