Easy maybe, but for sure a pain in the a$$

$500 to have some welds and flex pipe done??

Shifter

Well when you say it like that it doesnt sound like much does it? I guess you just dont know what goes into it.

Lets break it down for you.
1. $300 for flex pipe install, and have brackets made to mate the pipe to factory mounting locations at sides of trans pan.
2. 2 hrs labor for welding all flanges and collector of header. Now remember to weld, you have to clean the metal(remove the coating), make a bracket to hold the flanges all straight so that they dont warp from the heat.
3. Have header recoated.
4. (no cost) remove and reinstall the header.

Sound about right now?

I don't know why you got so much trouble, i got a new set from Kleemann, installed $350 so far for the last 9 months enjoying it without any issue.

berti_00

hey am getting a set of kleemann headers as well... anything i should be looking for?

Now my secondary cat delete with flexi into resonator does not sound so bad at $1000...

Still allows me to plug in mid section with 2nd cats for tests

Shifter

Welds that did not penetrate.

CharlyE500

Get a new set instead of used. They are already so cheap.....

berti_00

yes i am getting a new set... corey is getting me all set up

AMG E Power

Sweet deal going to have C2 install them for you ? When will u have them

berti_00

no am going to have a guy that works at the clearwater mercedes benz he has his own shop at his house with lifts and all and does welding as well... so when he installs them he'll weld them and have it all done... while doing them doing the motor mounts tranny mount and the ASP pulley kit... and than installing the python tubes l and then sending the ecu to jerry to have it all re-tuned

should set me some bad *** power and sound

AMG E Power

Hell ya man I didn't know u were gonna do a pulley kit as well, which size u going with ?
Power and sound for sure ! U will probably be making 580-600 @ the crank and 500 to the wheels dibs on a ride when it's complete !

berti_00

BETTER hold on tight to the seat lol

berti_00

OP did you end up still putting the 02 sensors on

Shifter

I am running the front 02s but not rears.

Triman2008

I have the same thing on my Kleemann headers, but when I do mine, I am going with long tubes......do big or go home. I will have the Kleemanns rewelded, and then put up for sale.

Kleemann..
Made in China!

Shifter

Well I had high hopes this would not happen but it did. left side header now cracked, already have it removed to be welded up like the right side.

Lesson learned, dont buy used no matter how "new"! I should have been patient and waited for the new batch of headers rather than gotten these! Hopefully will be re installing this Saturday and have the 55 back on the road again.

berti_00

Dammm thats gotta suck

AMG E Power

Hopefully mine hold up to the test. Good thing these come with a warranty
Still probably a pain in the a$$ if they do crack tho

jcjmw

Yeh, my passenger side at the collector point also cracked. It was a pain to get it off, rewelded amd reinstalled. But, no more problems and its still a great header.

The new Kleemann headers I just bought are different than the old versions that I see pics of...The header flange is not welded in place, it is loose over the flange, maybe this is the fix for the cracking flanges, all the other welds looked really good and strong especially around the cyl head flange. Installed them today and off to the muffler shop tomorrow to weld the downpipes....Install was easy took me about 3 1/2 hours, no surprises. An offset 10mm Gearwrench really helps. Really excited can't wait like a little kid xmas morning hahaha
