M271 header special...again!
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
Am I gonna get better MPG with this kit?
And, what kind of saw you used to cut the pipe?

Who cares how it looks, as long as it performs

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!!

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...

Lett see what Cory says about it.

"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."

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

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??

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.
