I am sick and tired of the W203 C350 M272 model being left out of all the fun. Ok, so there aren't many on the street but they always seem to be left out of the mods party! Just look at the title of this forum! Where the C350?!? Forgotten (or excluded)! Here's what got me started on my ranting. I checked out the Remus Exhaust website today and they had a part number for an axle-back exhaust system for the C350 so I wrote them about it. Turns out it's for the W204 which you can't even buy over here yet! There are zero on the roads yet they have a decent exhaust system out for them. And none for the W203 of course which has been on the roads for over 2 years now. So I was hoping W203 C350 owners who have done performance mods will list them here. What fits. I'd like to see them fall into the following categories. If you have any first hand knowledge about parts that fit in these catagories I'd love to hear about them.

Mufflers or silencers -

Axle-back or cat back exhaust -

Air boxes /cold air intakes -

Headers -

High-flow cat pipes -

Shifter / linkage -High-flow resonator pipes -
Cams -

ECU reprogrammers (93 octane) -
Manifolds -

Turbos / superchargers -

Fuel injectors -

Throttle bodies (?) -

Transmission reprogrammers -

Wheels (18"/19") -
Air filters -

Lowering springs -

Performance shocks -

Sway bars / bushings -

Brakes (calipers/rotors/pads) -

M272 is the 2006-2007 C230's engine.

rlee02135

Most W203 parts from other models will fit the C350....

same car, different engine.

Drop-a-Daimler

Oh, sorry. I thought the M272 E25 is in the C230, the M272 E30 is the C280's 3.0L and the M272 E35 engine was what I had under the hood, the 3.5L 24-valve DOHC SFI 90 degree V6 with the aluminum block and silicon/aluminum lined cylinders.

PS: That is the second time I have tried to wipe your bug off my laptop screen.

MBUSA specs quote the front calipers as dual-piston. Typo on your part or did you upgrade your brakes?

MBUSA website isn't always correct.

Seems like all the C350 SS's got the 4 piston calipers from the C32/C55.

drexappeal

Some 350's (I think in '07) ended up having 4 piston, just like the 2004.5 and early build '05!

sanf

seriously.. that bug is getting to me as well. lol

BadAssC230k

07 c230 brakes were 4piston too. if they arent, then they are surely some BEEFY 2 pistons

e1000

2007 C230's do NOT have 4 piston calipers, they have 2-piston calipers.

Drop-a-Daimler

No, it's correct, the 2006 and 2007 C350 Sport Sedan models (W203 M272 E35 to be exact) get 4-piston calipers up front with the cross drilled, vented rotors all the Sport models got. So in most wheel catalogs you will find almost no wheels for that specific model (without crazy spacers). And if you do see a part number, then I would ask specifically about the fitment because some suppliers I have talked to will sell you a general W203 wheel and it will not fit. That's one reason why I avoid the "most W203 parts will fit". As it turns out, when you dig a little, mufflers are a toss up, wheels don't, headers don't, and cams don't. So buyer beware.

e1000

easy thing for wheel fitmet is just lookup wheels for the C32 or C55.

drexappeal

Well, I'm not sure I agree on why the 350 is not listed in most catalogs. My theory is that it is an engine that is 2 years old and realistically, to get wheels, all a w203 owner with 4 piston calipers would need to do is check for the C32 setup. No reason for wheel companies to re-do all of their catalogs, just to indicate the 350's, which have the same brakes as the 2004.5.

Believe me, that's how I had to approach buying wheels. Every single set-up I saw, I had to look at the C32 setup and nothing less in order make sure that I was getting a setup that would clear the front brakes.

BadAssC230k

your right. my bad. just beefy dual piston with cross drilled.

MiKeSSw203

me too Damn you Robert!

Drop-a-Daimler

It's a valid point and I tend to agree. It's how I started my search after seeing NO C350 part numbers. But I am always still wary. The AMG calipers are 4-piston but look slimmer so I still try to verify.

drexappeal

I have the same exact 4 piston setup. So, if you need verification, my setup clears without ANY problems (although, I do have 3 piece wheels). Anyways, when I was initially ordering, I told the shop to base the setup on the C32 setup.

Drop-a-Daimler

Cool. Good tip. I've added it to the Wheels section at the top.

AndySays

I think both the sport 350's ('06 and '07) came with 4 pistons, last time I checked was in my garage

We just got confirmation from Remus Austria that our C320 exhaust system will fit the C350 W203.

good deal Mathieu !

Drop-a-Daimler

Man, you guys are fast. I just got your email confirming this fitment and came here to update my thread and ... it's already posted!

Any thoughts about improvements since the C320 makes considerably less horsepower than the C350 (215 vs. 268), is there a risk that the C320 system will be restrictive when applied to a C350? The pipe diameters appear to be the same.

Saprissa

if the pipe diameters are the same, then it wouldn't be restrictive.

REMUS

Email has been sent to answer your question.

Basically, all our Sports Label exhaust systems are straight through, since the diameter of the piping is the same, performance will thus not be affected
