The exhaust still needs the final touches. Final pricing has not been decided.

I just wanted to show the development of our C63

C63
Does the valve exhaust include the muffler and tips?
I have yet to see a cat back exhaust built for the C63 (besides MHP). It would be awesome if we had more companies making this. Preferably a bolt on system were the resonators get deleted also.

Looks like a great set of Mid-length 4-into-1 headers; similar to the Cargraphic or Supersprint design. They are not a long-tube design.

Exclamation Long Tube...
As the Mercedes C63 definition of long tube headers states "If any collector is located before the final bend it is not a long-tube."

RED - Final Bend
Green - Collector

Our collector is after the final bend there are no bends after the collector...

You've got that backwards. You've circled the front of the 4-into-1 collector in red and highlighted the final bend (in the straight pipe) in green that follows it.

Here is an example of a 4-into-1 collector on a set of long-tubes. Notice it is parallel to the ground?

So we are clear the slight bend in the pipe doesnt make it long tube?

Exactly. Those look very similar to the Cargraphic headers. (Mid-length 4-into-1).

We will agree to disagree...
I've got tons of feed back from header manufacturers. Guys that specialize in long tube headers for the American muscle cars old and new. All i got was mid length and long tube responses. oh well...

Yup. The entire system (from headers-back) looks identical to the many Cargraphic-like systems out there.

This thread covered a lot of the details -> https://mbworld.org/forums/c63-amg-w...er-system.html

Vivid, I thought you said this was designed in-house?

Yes everything was/is designed in house.

I'm not surprised to see a header that looks like ours, it was bound to happen.
