Anybody here know anything about 9ff tuning Mercedes?? My buddy has a 9ff variotune exhaust on his turbo. It sounds incredible. The killer thing is that you can turn it off/on.
It makes power everywhere, but allows you to mute it when you want.
I think that’s pretty cool. Anybody know if these guys make one for MB cars? Is it at all possible to adapt something like this to an sl55??

I think that they are Porsche Only.

i had one on the 996 twin turbo that i just sold.. they are great.. cost me about 7K.. i took it off and am now selling it on 6speedonline..
.
i am thinking about buying something like it for my SL55..
.
i believe that this company is making them for MB.

kreisseg...$22k for an exhaust...that doesnt make power...they supposedly sound pretty good.

i'd think for $22,000 it should sound half way decent..
