Supporting hardware for downpipes?

[E92TiAg335i]

Hey guys. I'm about to pull the trigger on some VRSF downpipes.

My M4 has 40k miles on it. I keep seeing all these additional options for "v band clamps" or "midpipe gaskets."

What supporting gaskets or clamps do I need when changing the downpipe?

Idk about clamps but you should definitely get new turbo to downpipes gaskets and downpipe to midpipe gaskets

Thanks!

Highly doubt ppl here replace the clamps, I did. IIRC BMW E-sys calls for replacements

If there's nothing wrong with your V-band clamps it's best to reuse them since they should fit easily. New v-bands can be a b!tch to get that first thread on so you can tighten. Make sure you have a pair of new turbo-to-DP "ring" gaskets and new DP-to-midpipe "flange" gaskets.

If anyone wants to buy the new pair of Vs that I still have left over just ping me.

Damn. All of that for downpipes?!?

When i did the downpipes on my n55, i just replaced a gasket and the downpipe itself, if i recall correctly.

My bad, thought I added the turbo to downpipe gaskets on that list.

Refer to the parts diagram on www.realoem.com to get a better idea. Here's one specifically for the downpipe: https://www.realoem.com/bmw/enUS/sho...diagId=18_1089

Here are the exact DP gasket part numbers needed for F80/82 M3/M4
