Will Aftermarket C63 Exhausts fit W212 E63?

Has anyone tried using any part of a C63-fitment aftermarket exhaust on a W212 AMG?
I ask because the two exhausts appear very similar, at least from about midway back to the mufflers, and there are a LOT more options out there for C63 exhaust systems.
Call me cheap, but I'm not prepared to spend three to five thousand dollars for a catback exhaust.

I've considered the various options for deleting the resonators and replacing them with straight, X, or H pipes, but I'd also like to know if using a full or partial aftermarket exhaust from a W204 is doable. I can cut/weld/modify the exhaust myself, so cost of labor isn't an issue provided they aren't somehow drastically different.

Has anyone tried this? Anyone know what's actually different between the two cars' exhaust systems?

Below are pictures of W212 and W204 AMG mufflers. Aside from the length of the mufflers and tailpipes, and the tips, they appear to be close enough to the same to require very little if any modification to fit on the other car.

Just looking at the pictures, I can't imagine them fitting without significant effort. On the bottom, the tips are set-off significantly more from the can than in the top picture. As such, some cutting, re-shaping and welding will be required. I'm sure it's not impossible, but it doesn't look like it will be an easy bolt-up.

The differences in the tips are what I would consider easy to fix. Cutting and splicing those parts is maybe one hour of work in my garage.

I'm more concerned with the rest of the exhaust. If the pipes are totally different in diameter or bent at drastically different angles somewhere, it might not be worth spending money on a full C63 exhaust vs. simply buying high quality universal mufflers and building an axle back.

I may give it a shot. If I do, it will be with something cheap like the Becker exhaust. Not looking to cut up something expensive. If I go that route, I will have to spend real money on headers, because I don't want a full Chinese exhaust system on my $90k-MSRP German luxury car

Headers alone will change the whole sound and make power. Not much power to be had on the catback section.

Thanks. I'm starting to lean that way anyway.

If you want sound, then do a resonator delete -- best bang for your buck when it comes to sound.
