Parts Development For C250
It would be great to get some constructive feedback on this from you guys.
Thanks-

Downpipes and exhaust would probably be one of the first things that we tackled if we did something like this. I'm not sure if we would do stuff like camber plates but an intercooler and pipe kit is definitely something that we could tackle as well.

@ World, FYI the exhaust for the C180/200/250 is the same.
BUT for the Facelift models.
The C250 pre facelift exhaust is a little different than the C250 facelift exh.

All three sections will be able to be attached to the factory exhaust components or they will be able to be used altogether. It will be made from high quality T304 stainless steel 16 gauge seamless tubing. The system will be all mandrel bent and will use all the factory mounts and flanges so there will be no fabrication required.
With all the parts that we make, you can expect the highest quality components that you should be proud to install on your car. We will also be working on many other parts for this vehicle but the exhaust is our first and you can expect production pieces to be ready to ship by November 7, 2012. We will release pricing as soon as we have that information available.
I have done custom quad exhaust on my C250 coupe - it is a little bit of a pain in the ****. First, the Cat feeds right into a lower support brace at an angle, and pipe almost immediately has to bend over that. And then shortly after there is a rear differential that gets in the way - so too quick and close together bends is certainly not ideal.
Additionally, there are no factory supports for a muffler on the passenger side on a C250. To add salt to the wound, the gas tank is shifted more towards the passenger side, so that both spaces are not even on both sides of the vehicle. This means that a muffler will have to be smaller on both sides, and also, that the exhaust piping leading to the mufflers will not be symmetrical. Also, there is a black plastic cover that needs to be removed with a few torx screws and a plastic clip in the wheel well.
Perhaps if you could revise the downpipe and either provide a smaller "performance cat" that will end up being higher then the undercarriage brace, then you could avoid at least one bend in the exhaust. Additionally, due to the muffler constraint issue, I have relocated a single Magnapack with Y-Pipe to the center of the vehicle, and straight piped to the tips. I love the sound, and one muffler is certainly sufficient, as the turbo definitely quites the exhaust down a LOT.
Also, a better intake for these vehicles would be awesome. The way the current intake draws in air, and bends it around is certainly not ideal. There is tons of room in front of the engine and behind the grille to do a ram air setup as well as prevent the need for any bends in the intake.
Those would be my 3 suggestions for the first three mods. I'm not really into changing suspension, lowering, etc.

I have a cat and downpipe for more than a year now, so it allready excist.
I know Kleemann is busy with it as well.
Quad exhaust isnt a big deal, the chassis for all the W204's (FL) are the same, the only thing we are missing are heat shields and an exhaust bracket.
But can be ordered by the MB dealer
What kind of tips will you be using for your exhaust?
The fty intake does a well enough job and is essentially a true cold air intake plus considering the ecu placement i dont think its a good idea to mess with the design. I have already suggested hard pipes though.
I would like to eventually see other options for strut bars and chassis braces sort of items. Renntech are currently one of the few if not only company ive seen so far that offer strut bars and in cf, but at close to $800 a pop its just not financially responsible for me to consider it.

Right now we have several projects going on so it prevents us from moving forward with the C250 full time but we WILL meet the timeframes that I list here and our products will be amongst the best quality parts available for any Mercedes, let alone a C250.
All of our products have a warranty and they will fit correctly the first time.

Also, on my C250 coupe, the exahust is not the same, as the placement of the fuel tank is different (from my prior C300 for sure, but I suspect also sedans). Yeah, of course the heat shields and exhaust brackets are missing, but it results in any exhaust system not being able to be truly symmetric, with differences in distance and bends on each side.

And we already have enough vendors that deal with ext. items, it's time to back up the looks.
As far as the intercooler options, someone mentioned that the oem is already quite large though I've seen a BMW FMIC which was large also and MHR managed to improve on that with a more efficiently flowing unit.
Turbo options I'm interested to see what your company brings. Boost controllers I'm somewhat wary of though given that MB links so many items together that if one of the links is altered the whole car might go
Has your company also considered an air/oil separator?
