Any DIY install for downpipe? X3M/X4M

Hi guys

Trying to find a good video/photo for a DIY downpipe install. Will receive my downpipe tomorrow. I do have a garage, some tools and a quickjack to raise the car roughly 2 feet from the ground.

I'm good with cars but never did that kind of installation. I did exhaust, bumper, CAI, JB4, but no downpipe.

So trying to get a good way to start!

Thanks!

It’s pretty easy on these, a couple bolts and replace gaskets. Plenty of room to do it in too. Might need a long ratchet exstension.

Here are the schematic's so you can see whats going on down there. Other than that its just a simple swap. Take care with the o2 sensors.

It is very easy if you can get the car high enough off the ground.
Itís straight forward to be honest.

One vband clamps you can get to from the top with turbo inlet pipe removed. The bottom v band you can get to through the passenger wheel side. (Thatís if car is LHD)

Just make sure to order 2 new turbo to downpipe gaskets and also new vband clamps from bmw (dealers always replace both when removed). Itís cheap to replace and itís for peace of mind.

Main thing is to take your time and make sure the vband clamps are seated properly.

I did them myself as well. I didnít take pics but can answer any other questions you may have.

just wondering. How high do I need to get the vehicle off the ground to pull the downpipes out from below? I don't have a lift.

Honestly I did it with quick jacks, so maybe a foot? If you can fit underneath, you can get them out.
