• Race video showing the difference between a C63 AMG with just an ECU tune and a C63 with an ECU tune plus headers and exhaust

      This video comes from two BenzBoost members with modified W204 C63 AMG sedans, users Mthis and JonsC63AMG. The modifications on JonsC63AMG are an OE Tuning ECU tune, everything else is stock. The C63 taping the race belongs to Mthis and has an updating OE Tuning ECU tune along with long tube headers, BMC filters, 3 inch mid pipes, and some lightweight mods. Despite a lead and jump by the C63 belonging to Jon the C63 recording showed the horsepower disparity reeling him in and passing him. Exhaust modifications clearly make a nice difference on the C63 and compliment a tune well.

        It's nice to read a few funny posts here and there after all the negative posts that have plagued this section in the past year or so.

        If you want to.

        I think you should modify your car more Jon with how you seem to not like to lose.

        Well with headers on the C63 is too loud. By doing the comparison runs with it. Its not worth it. Unless it has a racegas tune which I won't have.

        Its subjective. You can run long tubes and weld them up to the rest of the factory exhaust and remove the secondary cats and it's not loud at all unless you are WOT. Cruising around you never know the difference.
        Catless long tubes and it's obnoxiously loud.

        When I was talking to Mthis. He said he has resonaters. I thought these would quiet the sound. But his car was really loud! Its weird my friends 2010 e63 has the prim cats deleted with stock pipes. Its only louder WOT. But cruising its quiet. No drone what so ever.

        So does this mean you're going to change your name to "charcoals-intact"?

        Yes to 130. At higher speeds it would be worse. I will put my money on it.
