wow!! great pics!!!!

ProjectC55

It has a runner for each individual cylinder(4) running into a collector that holds 4 pipes. That is optimal. However your setup is tru indeed better than stck. Kleeman E55 header:

E43

The Kleemann headers are louder than stock, but not by too much. The car is still very civilized. You can only hear the difference when accelerating. When I am crusing around town or on the interstate, the car sounds stock. If you install them on your S Class, I think there will be less of an increase in sould because you have more sound deadening. Kleemann claims an increase in both horsepower and torque, but I have no dyno figures to justify that. The throttle response is much better, and the car feels faster during acceleration.

E43

Thanks for the pics. I am surprised the design of the E55 headers is different than that of the E430 headers. It seems to me that Kleemann could have used the E55 header design on the 430 and had an even greater power increase.

ProjectC55

That's why I can't figure out what Kleeman was thinking! The W210 E55 headers I'm thinking look like the W211's.Those are the one's posted in that link. W211 E55.

The e430 header looks to be a tri-y design while the e55 header is more of a traditional 4 into 1 design. Tri-y is generally used to boost low to mid range torque and is very popular with street driven 1960s Mustangs. The 4-1 helps more with top end hp based on my BB Ford experience.

E55 PWR

I agree, no offense to whoever purchased them but that is a very inferior design, thumbs down for kleenman for half assing their headers that cost so much. probably still much better than stock but they should have done 4 individual runners per side.

ProjectC55

I believe the C43 headers may be built the same way. I was told 4 -2-1 style but that will work good only if they run Cyl 4 and 1 together,and cyl 2 and 3 together into 2 individual pipes going into one huge 2.5 inch collector. Same goes for cyl 5 and 8 together and cyl 6 and 7 running into 2 individual pipes and into one 2.5" collector. I'll probably still get them and have a fabricator try and set it up how I like it.

In this pic it looks like the passenger side header is built correctly for a 4-2-1 setup based on the order of the power cycle. Better exh scvanging on the passenger side vs the drivers side. Perhaps this is a minimal thing here I don't know



The drivers side of the E430 might have an issue with space perhaps as to y the drivers side header is built as it is I think. I know Kleeman said that this was the issue with the C43.

I guess the bottm line is the poster noticed a power increase!

ProjectC55

I believe that's the other way around no? 4-2-1 will give more mid and high rpm power. 4 equal length into one will give you good power at a certain pt in the rpm range. That will more than likely be power at the low end.

Quick question. I wanted to take my car to a muffler shop to get the pre cats taken out and just have an O2 sensor run into it but they told me that it was illegal. Is that a state to state thing or is this possible and they don't want to do the work. I have to get my pre-cat replaced because it's starting to rattle and it makes the car sound a bit "dieselish" at times. I don't want to replace the whole cat converter setup (expensive!) so I just wanted to do just the part that is messing up. What do you think?

ProjectC55

I believe that's a Federal thing! If u don't live in Cali get the headers and be done with it. No more MB precats which will run more or about the same as the Kleeman headers.

Car making a humming noise.

--------------------------------------------------------------------------------

I have a 99 E320 with 122k on it. I noticed a while ago that is was making a humming noise that you can feel in the pedal when traveling at about 40 miles an hour and up. At first I thought it was the tires. Got new tires, problem still there. I do know my cat converter on the driver's side needs to be replaced but I don't see why i should get this noise from that. It gives a buzzing feeling in the pedal. Really weird. I tried driving hwy speeds and putting it in neutral but I could still feel it. What could this be folks? Please help, i don't know if something's going bad in the car.

ProjectC55

Bad tires are canceled out because you bought new ones I'd assume. How about your wheel bearings? My cats made an annoying rattling sound. My secondaries that is.

E43

coolcarlskiC43 is right in that it is a Federal law. To be honest, I don't know what the law says, so I don't know if I am violating it. I think some shops are wary of messing with any emissions equipment, so you may want to talk to other shops to see if anyone else is willing to do the work. When I spoke to Cory at Kleemann, he said his CLK430 passes Colorado emissions tests with just the secondary cats. He also said that half the power increase from the headers is created from removing the primary cats. This would be an inexpensive way for you to make more power, but you will have to extend the secondary O2 sensors back behind the remaining secondary cats.

John H

4-2-1s are a torque design which is why I suspect Kleemann chose it for the e430. If I recall, the e430 is about 100# of tq short of the e55.

4-1 headers pump up hp. As a general rule, the bigger and shorter the pipe, the higher the hp peak. However this is often at the expense of low end tq.

ProjectC55

So to keep the CEL in chk I'd have to move my 2ndary O2's behind the sndary cats?

John Major

Yeah I don't get that right there. How can you move the secondary O2's behind the secondary cats if thats what they're in already. Don't you mean the primary. I dunno. i'm not that benz techy yet.

E43

Yes. It's my understanding that on a stock car the first set of O2 sensors are before the first set of cats and the second set of O2 sensors are in between the first set of cats and the second set of cats. That's why on my install they had to relocate the second set of O2 sensors.

Here's a good read I found:

ProjectC55

Did u dyno the car yet? How has the car felt thus far to this point?

E43

Unfortunately, I haven't had the time to dyno the car. The car feels great up to this point. I am really enjoying the sound, the throttle response, and the extra power.

Do you have headers on your car? Are you condsidering Kleemann headers?

ProjectC55

Yes I am considering them. But I'm really curious to see what your car is dynoing.

Fabio D

I know this is an oooolddd thread! but want to clarify to all. the E55 headers you post (4-1 design) is only for the W211 E55.

In the W210 chassis the kleemann design headers are the same for the E430 to the E55

Just searching
