Lets start off by saying that I am very happy with the product and have been for about a year now, but I have come to some problems that are easy to fix but just a pain to get done. It came time for my first smog check and of course the first thing to note is of course they are not C.A.R.B. legal so they failed the visual inspection to start things off. I now am forced to switch out back to the stock header just to pass smog Not too much of big deal but just a waste of time. When the shop went ahead to remove the header they stumbled upon a little flaw with the product.





The header seemed to have either warped or there was already a preexisting unevenness with the face of the header that bolts to the block. As you can see from the pictures of the header and the header gasket there is a clear leak at one of the heads. To fix this I apparently have to get it machined to get it flush once again to get rid of the leak.

So you guys with the m271 Kleemann header, when you guys go in for your smog I hope you guys take what I have posted into account. This would be so much easier if the product was C.A.R.B. legal Maybe Cory can mail us the necessary kleemann plate with authorization numbers so we can weld them onto the header

ROLLNNN

Whats up Charlie,
Did that one guy with the other coupe at the Burbank meet, tell you you had an exhaust leak from your header? was that you?? damn, looks like he was right..

i think i have to smog mine next year, you think if i take it to a place, that will look beyond the header/visual inspection it will pass??

sucks you have to take it off, such a waste of time...

CoupeCrazy03

Yeah it wasn't just leaking from the header, it was also leaking at the downpipe where header connects after the fist O2 sensor because there was no seal ring to begin with.

I couldn't really tell you if you would pass because I never got passed the visual. I would say yes as long as there are no leaks of any kind

Not to worry though, as soon as I pass smog I'm slapping the b*tch back on

sorry to hear the trouble!

i haven't had any problems with my headers (thank god)... and am lucky that virginia doesn't do smog checks.

i recently got a safety inspection to renew my stickers and they didn't say/notice a thing. however, they scratched my front window tint and threatened to take my sticker back. but it was too late since they noticed after they passed me. i guess i'll have to find a different place next year.

keep us posted on the progress. how much was the labor to switch the headers?

That’s too bad about your leaks. WTH?

My otherwise diligent smog guy never noticed its aftermarket exhaust manifolds. Tailpipe blew almost as clean as a springtime breeze anyway.
Perhaps that bottle of his preferred beverage received during each Christmas holiday season improved his vision.

More than one enterprising member (M111 pictured) has fit a heat shield on theirs to help ensure compliance..

Lucky!!

I went to a friends shop so I should be getting a deal, not sure until its out of the shop. Will update for sure, but I have to figure out something before my NEXT smog check

Cheeky ******* That is some real creativity right there!

SeaCoupe

Splinter beat me to it. I would have left and gone to a different smog shop. However, in your case, you did need to get the warpage solved. A good machine shop will get it out the warpage, no problem.

I think the creative member said the shield was from some asian car.

Yeah although it is a friends shop, I am taking my business elsewhere for sure my next smog check.

Anybody know of a place in the SD area that will look past the visual portion and not be so damn ****?

XsuperbeeX

I know place in LA... not here...

C230 Sport Coup

yeh, with an order of flied lice....
you know it's not from an asian car foo....
stock shield, tin shears, a few studs and nuts, + a rain gutter bracket....viola!

I'm due for smog again....

How are you bolting up your stock manifold? didn't you have to cut your stock downpipe and clamp it to the Kleemann pc?

CoupeCrazy03

I still have the piece of the oe pipe that Group 5 cut so the shop is doing something with that for a temporary fix just to pass the smog check. I may have to rig up a flange on the downpipe so I can simply interchange if this happens again.

Before I go and do that though, do you have any options to my predicament?

CoupeCrazy03

Passed smog with stock header and eisenmann race Driving stock header sucks!

MiKeSSw203

congrats I guess lol

Just was wondering what others were doing. Did Group5 weld the stock pcs back? or rig some kind of clamp like how it was attach to the Kleemann down pipe.

I didn't want to cut mine and had an extra MB pentagon or so shape flange so I had a muffler shop make the pipe extend to the middle of the car and weld everything up that way it all unbolts and my stock bolts right back.

Petje

Thats the known "problem" , they forgot to send you the ring/gasket between headers and cat?? Like in this picture?



That was alos my problem when i got the headers, have gone to 10 diff. parts shops to find a gasket that would fit.

Kleemann told me that the gasket wasnt neccesary (wow dont know if i wrote this word correct ) because it will seal itself when the exhaust is getting on high temperature. WRONG!!!

So if you gonna instal the headers again, look for a gasket between headers and cat.

CoupeCrazy03

They welded the oem pipe that was originally cut back on to fit the stock pcs back on. Is it possible for your to post a picture of your set up? Sounds like a much better idea than the original install instructions from Kleemann

Oh I was able to email Cory from Kleemann about that seal ring gasket and he mailed it to me for free

But about that pic. . . why does that header have a Kleemann plate welded on it and mine doesn't??? If I had that, this shiz might be C.A.R.B. legal

Petje

Dont know about the plate, has to do with the production or something.... see the differences between the M271 headers... i dont have the plate on it, but it says nothing about emissions, but only M271 i thought.

Also the connection to your cylinder, the 4 pipes are connected by yours, by mine they are not connected... all had to do with production i think... I think Kleemann dont produce them itself, but lett another company produce it.
