Am I right in thinking with a c180k coupe you can not install header, kbox and a renntech pulley as the k box is not designed to work with a pulley as kleemann do not do one for the c180k only the c200 and bigger engine.
I want to get a pulley but then would I need to get rid of the kbox (which cost me £950 5 months ago) and have a remap done to account for extra boost from pulley?
Cheers

 

awesome! mine is supposedly waiting for me when i get home from work

 

Mine wont be here till the 3rd according to fedex

 

I know this dumb questions.....but

Am I gonna get better MPG with this kit?
And, what kind of saw you used to cut the pipe?

 

you guys better wrap those up in hear wrap or headder wrap. It'll make a huge difference

 

Congrats, do you also receive the gasket between headers and downpipe?? I dont see it on the picture!!!

They forgot to send it when i received my headers....

So you have to look if you received it!!

 

Hey Lindselld, also here on the US board?

 

will it really be that noticeable??

cuz if you wrap it, you wont see how sick it looks!!!

 

On my DSM it was noticeable, and overall a good idea. But I also had a big turbo and external wastegate that dumped into the atmosphere 2 feet away from the block. Considering how close together everything is under the hood of the W203 it probably wouldn't hurt. At least cool down the temps - which obviously will always be beneficial.

Who cares how it looks, as long as it performs

 

I have no gasket between the header and downpipe. What does yours look like?

 

Where did you find the gasket?

 

Because i received my headers on Friday and must fitted it on monday i have bought it at a local parts supplier.

But if i were you i would get the oem one from kleemann

I check for you if there's an oem one you can use on EPC......

I have looked at EPC and there is no OEM gasket, so i think they forgot to send it to you, isnt there a gasket in one of the pipes??

You def. need a gasket, because the two pipes are both conical, so you better send cory an email...

Lett me know what Cory say about it!!

 

Here you see the gasket on this picture.... think thats the one you need!!

Another thing, before you cut your original exhaust, first install the headers, because if it dont fit and you have allready cut your exhaust you can not drive..... Dont think it wont fit, but if you wanna go safe do it that way...

 

Thank you for the heads up!! I have already sent Cory and e-mail about this.
I also notice that I don't have a logo anywhere on the header or downpipe. Not sure why.

 

They are slightly different than my headers, but that can be modified or something. I have the kleemann logo on the headers and on the downpipe.

Your downpipe also looks a little different then mine.

Lett see what Cory says about it.

 

I am a noob at all this mechanical thing but what is the long metal sheet with the 4 hole on infected's picture is that not a gasket?

nvm i have just re-read what you said is the gasket for the header and the down pipe...

My header has finally arrive in the country but on the side of the continent

Wont get it till Tuesday since Monday is a public holiday ahhhh

 

This is what you should get in the box ... and this is what the header will look like after 20 mile road test. The gasket that is being discussed will be attached to the bottom of the header or cat flange its just a round metal ring. Hang on - look at infected post 74, has an extra piece welded on thats probably the 'O' ring to join the header to the cat, If you look at mine and Petje's cat's we don't have that extra bit welded in hence the seperate 'O' ring or gasket. Hope that helps.

 

Yes, that ring wasnt attached by my headers... so i have another gasket now....

 

i have no experience with this, but there were several sites against header wrap and for ceramic coating...

"Should I use a Header Wrap?
NO! ABSOLUTELY NOT. There is nothing that will damage a header faster than the use of a header wrap, other than attacking it with a hammer or shot gun. As advertised, these wraps do keep the majority of exhaust gas temperatures within the header. The result is the wraps will prohibit the header tubing from cooling properly. If you reduce the ability for headers to dissipate adequate heat properly, the result will be premature failure of the metal. Depending upon the application use and temperatures involved, the life can be reduced to only a few hours. We consider exhaust wraps to be the header manufacturer's best friend.

If engine compartment temperatures are an issue, the best solution is to use insulation materials on the sheet metal. One alternative in some applications is to build a box around the headers and actually duct outside air into the box. In some applications ceramic coatings have been known to help (see notes on coatings above). Insulating any components that may be sensitive to heat, such as wiring, fuel & oil lines, etc., are a better option.

IMPORTANT: Use of header wraps will void any warranty."

Any news from Cory ??

 

From Cory:

Nope, no gasket. These headers are designed the same way factory V8 MB exhaust systems are- there's a seal "ring" welded to the header, and the flange on the down pipe is swelled. The swelled section of the down pipe seals against ring that's welded to the header. As the header gets hot, the metal expands, and seals.

If you guys look at the pics, the whole set up is slightly different. You can tell by the flange on the header; it's one piece rather than individual.

 

WOW...damn good steal

 

yeah it is, but the header will look prettttty nasty after a few 100 miles


idk about ceramic coating. What I'm talking about is like a fabric almost. You wrap the tubes of the header with it. It really does make a huge difference

 

so if you put the ( to the ) you het () and that will seal without a gasket

Never heard of that, when i received mine i emailed with Kleemann and they forgot to put the gasket in the box.... but if Cory say so....

If the header has an end like HEADERS) and the downpipe like )downpie than it will fit together like ))
(hard to explain... LOL) but you can never put ( to ) in my opinion.

Can you make a better picture of the ring on your header??

 

I have found an example to explain....

If your headers had the same "ring" welded like this :



Than you can put it on the swelled flange from the downpipe



Thats how most exhausts these days are connected, my rear silencer is also connected to the middle silencer this way.

But if you have the same swelled end on the headers like on the downpipe, there's no way to close that.... By my headers i had 2 swelled pieces, the same as on your downpipe was also on my headers..... so i had to visit 10 local car part shops to find a gasket, because it's not from this time anymore.
