Finally had some time for work on this one, made the exhaust and started mounting up the intercooler.

What the downpipe ended up looking like, decided to dump the wastegate into the main exhaust:

Flex fitting for after transmission mount, hopefully will reduce stress on the turbo:

Installed:

Added a couple bolts for adjustment on the w220 mount:

Here you can see the temporary transmission mounting, a W220 pate grafted onto a W126 pate with some support metal welded on. Someday I'll make a nicer version, but this will work for now.

I built the exhaust in three pieces with band clamps for ease of driveshaft service and rear differential/cv swap.

Don't mind the booger welds, here you can see I had a few too many and forgot to turn on the gas. Amazingly, the pipe still holds gas, not pretty though.

I used all the stock mounting points I could. I may still add a lateral brace between the old kidney bean muffler mounts once I get done under the driveshaft plates and finalize everything as there is too much side to side movement for my comfort.

Patchwork of W123 mounts grafted onto a couple pieces of metal:

Still not sure how well this W220 AMG muffler will do, hopefully will get to find out soon enough. I put one of the resonators from that car on my om642 and it seems to flow just fine, this one I'll add a resonator if it is too loud but want to try without first.

Tip alignment (she tells me this is important)

Went for the biggest intercooler I could possibly cram under the bumper:

It will work, but is going to have some mild modifications:

The front pull is in the way:

I made some cheater plates to hold the bumper out a little more. Off of these I'll build the mounts for the IC so modification of the body is minimal.

I want to keep the bumper as stock looking as possible, worst case I can take off this lower support bar and redesign the front lower radiator support, but really trying to make it work without that first:

Have a couple mm around the sides and bottom, that is the lower lip of the bumper and bottom of the IC:

Will keep updates coming, hopefully more frequently than yearly...
