Doing a VRSF catless downpipe install on my 2014 F30 328i xDrive (N26). i was told I needed a 4inch v band clamp because more than likely my stock one will break. Any links or product numbers would be greatly appreciated!! I have been trying to look for some , but only find ones for the N20 :

That one is 2 1/2 inches, I need 4 inches :/

The site above is correct. There are 2 clamps you may need to replace. Several threads on this but you’ll want to have these 3 parts on hand.

18307581970 gasket
18307606136 screw clamp
18307628660 muffler clamp

Just asking is the midpipe 4 inch...too.

I just google 4" v band clamp... they are in there... ebay, amazon and other places. There won't be an OEM 4" for n26

Number 3 is the 4" clamp from RealOEM. Its the turboside clamp that can break as well. The midpipe side one was tacked onto my midpipe but it was fine to reuse.

Man, I installed the catless downpipe on my n26 myself and that v band was Forsure the hardest thing in the install, I just couldn't get it to clamp down fully so that I could get the bolt in,
What I ended up doing was having my friend position the v band clamp and then at the connection point to where the bolt goes into he used a plier to fully clamp it down to where it locked the downpipe to the turbo in place at that point you shouldn't need to have to hold the downpipe up anymore as that clamp will do it for you, that is when you know it is locked down, then you just put the bolt in
ofc I changed the inside gasket but reused the original v band clamp, ended up destroying the mid pipe clamp tho

Could be anything from the clamps being loosened, the transmission bracket being loose, the mid pipe being misaligned or your exhaust tip hitting your bumper (which was what happened to me) super annoying Forsure and yes eco pro creates a deeper tone/idle and I'm not sure why but I've definitely noticed it

OP was just asking for part #

Anyway back to your post.... you don't install from the exhaust back to the dp... that is backward..

You need to loosen up the catback exhaust (if you have one) if it is stock loosen the hangers. Install the dp first then aligned the exhaust and tighten up

Oops... Oh yeah I went from the turbo back when installing, that way the exhaust mid pipe could just be popped back on once the downpipe is set in place
