300E a couple 1994 w124wagon E320 Wagon/,1971MGB Track/Rally, MG Midget Autocross ,2000 E320 wagon.
$1400
bucks for 12 H.P. ?
I'd pass on it even if they did have an application for the 1998.
You can pull your own manifold send it out to be extrusion honed and ceramic coated in and outside for Less than half that amount.
You could send off your intake manifold and have it Jet-Hot Sterling aluminum-ceramic coated (only outside,the inside you want factory finish)and still be up $500.Both units will be show car shined perform and look better.
matched diameter primary tube? This is not a tuned length header it is a 25 inch long exhaust manifold
You might gain a little on the flow you get the same from coating the oem units and the drop in underhood temps alone will give you more that 12h.p. out of coated oem units.
Ship off your 1998 unit,save your money.

I would be wary of any company that has to ask a w210 m113 engine car owner if they have 3 or 4 valves.

Extrude Honing will loose TQ as it makes manifold too big. I have tested this back in 1999 on several cars.
On a normally aspirated engine we use 1.625'' primaries vs. 1.75'' for 55 engines.
1998 was transition year from 4 to 3 valves, a lot of owners assume one way or another, this is why I asked for clarification.

ohlord while i agree with most of what you said isnt the 210 e420 a 4 valve motor and the 210 e430 113 3 valve? Thats probably what he meant.
This manifold reminds me of the powerbomb mod(as we call it here) for tight spaces or wierd exhaust setups that restrict fabrication possiblities. What programs or mathmatics do you use to make these? Or do you do what i do and screw up 600 times before you find something that works? Wouldnt you want to put a positive curve towards the outlet on the 2-3 and 5-6 pipes to increase flow? Haha what am i saying? Look at that red headed step child of a manifold i made!

Two key factors made the design:
Tight space and bolt-on installation.
No doubt a full-length headers will make more power. What I found testing different designs, is that with a vary mild cam timing that stock engine have, tuned header does not offer any advantage over properly designed HiFlow Manifold.
Secondary, most owners either are not willing to cut and weld exhaust systems or do not have an access to the shop that is willing to do it.

You should design some turbo headers for the E class mercedes. In the past month on mercedes shop . com there have been 3 done, two TT 300e's and a single 300ce. Most would prefer a T3 manifold to start with but do not want to go through the massively insane headaches of making one themselves.
It was too late when i realized there is a perfect space just under the manifolds of a 210 e320 that allows you to drain oil without a pump in which you could just make a pre down pipe straight to the turbo.

We did
an extrusion hone and coat on V8 and a V6 m113 and m112 3 valve engines neither suffered from the torque drop,the rest of the under sized exhaust system still provided enough restriction to keep the torque curve down low.
Your unit looks well thought out and constructed.
I just think some tuning to extract the greater gains would show a better chart and greater sales.We installed an H pipe in the system and rid the car of the motor boat sound so common of resonator delete cars and it woke up the dyno numbers.Was you unit on stock pipes?
One more thought ,market this manifold as an alternative to headers.Some of the high priced units from other company's are a lot more money than your item and from what I have seen offer none of the advantages of a heavy duty free flowing leak free manifold.Look in the amg forum ,it's like they have to rebuild the whole unit before they can install it.

I have no idea if my car has 3 or 4 valves and understood very little of what you guys are talking about. Just thought I'd point out that the 98 wasn't covered in the offer

the other stuff is go fast lingo,you will understand it soon enough when the bug bites you.

Can someone please explain to me why these are so expensive? You can get headers or manifolds built for any domestic car for $200-$300. I think this is just madly over priced and ripping off Mercedes Benz owners! Looks like 800%-1000% profit because they fit a Mercedes! Explain to me why Doug Thorley can make headers for a 300C for 1/3 the price your asking for your manifolds? $663.00 Retail! You want to be a good vender to the people on this site..quit trying to rip us off and drop the price to a reasonable amount!
