Anybody know who makes exhaust for c43? Where to get, and how much? Price not really an issue

NitrogenBalance

I'm 99% sure that eismann (spelling??) makes one for the C43. There is a post in the W208 CLK section with a sound clip for someone's CLK430. It sounded pretty nasty. I would imagine the C43 may sound a tiny pit meaner.

I'd post the link but I couldn't find it.....

Eisenmann and Supersprint for sure

SDR

The Supersprint resonator can be found for about $450 and the muffler for about $525. From what I've seen the Eisenmann is about 25% more expensive.
The budget option is to remove the resonator if you're just after a deeper/louder sound. This takes a little work from your exhaust shop since it requires a Y pipe from the cats to the single muffler pipe, but any decent shop can manage it.

I am curious, what is the point of putting an aftermarket exhaust on a car already engineered for max performance? Do you gain much in HP?

Well if your C43 exhausts need to be replaced, M-B ask a lot of $$'s so it's worth looking into alternatives. Over here in the UK Mercedes Performance (that's the name of an independant company) provide the Eisenman back box which they say frees up about 5bhp. They also supply high performance cats which free up another few bhp. They can fabricate a stainless system to replace the front section and reprogramme the ECU. Altogether you get another 60bhp - say 20 bhp from the exhaust mods and 40 from the chip, by memory. I'm not really into modding these cars but I might consider the back box/cat option to free up a few more bhp for less cost than the original Merc parts when the time comes to replace the parts.

You'll never get 40bhp out of chip tuning.
That said, there are other reasons for a new exhaust too. In addition to the nominal power increase there is weight reduction, appearance and sound quality.
The stock C43 exhaust is pretty efficient (Sebring IIRC) and is built to last. The primary drawbacks are that it's rather subdued in sound and is a bit heavy.

Come on though, appearance is bit of a stretch, the twin AMG tips look damn good if you ask me.

SDR

Oh I never said I wasn't happy with the stock appearance, but I've seen people do all sorts of things I find tacky - even to an AMG
My personal opinion is that it isn't worth the money to put one of these systems on unless you are serious about track times. And in that case you're probably running an M3 anyway

...... ............the gas pedal is on the right.

Agreed! Also the best feature of Mercedes' is quietness in my opinion.

I thoroughly enjoy it's subtle throatiness during normal driving, or the way the house rumbles when I start her up in the garage and forget something and have to run back in. But, if you punch her, man, she does love to growl.

Looks like the jerkoffs at SS raised the price of the reso another 125.00. Unbelievable!I waited too long and I need a new Reso section now.Looks like I'll have to go dual pipes from the high flow secondary cats back to a Y pipe which Flow Masters makes all the way and eliminate the reso for cheaper cost,more noise and perhaps a tad better performance!

SDR

I had my resonator removed for $90 which included custom fab work (they built the Y and mandrel bent). The result was .. well.. almost unnoticable. It may help performance, but not enough that any SOTP dyno would pick up What I was happy about, however, was that it doesn't make it obnixiously loud. In fact, at ide it's barely noticable at all. The weight savings may be the biggest benefit and even that's got to be nominal.

ProjectC55

Well as long as you say it's not loud,then I'll go with a dual pipe mod to y-pipe towards rear instead of going with a SS reso!

Angus London

I've found the original email and here's the breakdown of (claimed) power increases

ECU upgrade 24bhp increase
Exhaust system 4bhp increase
K & N High Performance air filters 4 bhp increase
Racing catalysts 20bhp increase

So the chip give a 24bhp increase and the rest another 28bhp - 52bhp in all.

I stress that I am not endorsing these figures, just quoting the supplier

SDR

That's probably a reasonable estimate. The irony of the claims regarding chip tuning is that the more reputable tuners - Kleemann and RENNtech for example - claim more conservative numbers of 10-20 compared to the 20-40 claimed by the lesser known such as SpeedTuningUSA.
I'd really like to see some real life dynos on these. When I inquire locally I get replies which include phrases like "under optimal conditions" and "results may vary." Such responses make me lean more towards the $800+ solution from someone like PowerChip, Kleemann or RENNtech. Although not claiming as much of an increase it seems like realistic numbers rather than empty promises.
As an aside, I just added the K&Ns to my C43 with the resonator removed and it sure seems more responsive, but without pre and post dyno numbers it could just be the placebo effect
