C63 diffuser / tailpipes install on C43 Coupe?

I've just bought an OEM kit that includes the C63 diffuser, tailpipes, brackets and mounting hardware for my C43 coupe.

I'm fairly confident the installation can be done without removing the rear bumper, but after watching this video:


...I'm not so sure.

Has anyone done this exact process on a coupe? Did you manage to get to everything without removing the rear bumper?

Have you done the install already, or looking to do it?

Spent some time under the car earlier, and while I do think it would be possible to remove the diffuser without removing the bumper, some of the clips / connectors will be very awkward to access.

Removing the bumper looks fairly simple however, and it will be much easier to do the diffuser swap with it off the car.

Hoping to get the time to tackle it tomorrow so will report back with steps / tips

I just did mine. Almost impossible to do without removing bumper. Unless you have super tiny hands and tools, not gonna happen.
Took it to a body shop and did all the work for $100.

Well that was certainly an experience and a half!



I am fairly experienced and would definitely rate this install as difficult. Even with the bumper off the car it was an absolute pain at times.

I can write up a list of tips and pointers from what I learned if anyone is interested?

Results are worth it though

Yes, I have to agree it looks great, is that a C63 valence swap or an aftermarket?

Thanks man

Wheels are from a vendor here I think their name is wheel-world. They are 8.5inch front 40mm offset so H&R 10mm spacers are MUST and don't use more than 235 wide tire or they will rub. Perfect size for fronts would be 235/35/19!! Then buy extended length bolts for the fronts. Rears are 9.5" I would recomment using 265/35/19 tires. Rears fit with no problems so you can go 275 if you want

As mentioned above, the swap of diffusers isn't as simple as I was hoping. I'm going to have a body shop do it, a little more than I was expecting.

Just get the quote from your dealer, the price should be the price, I paid retail price less 15%. Let me see if I can find the part #s, they are on the invoice if I can find that thing. I'll look.
