Latley I've worked hard to try and bring some competitive prices on my headers. So for 1 week I'm offering E55/CLS55 long tube headers at a sale price if $2,999 a savings of $500!. To make it a bit sweeter I'm also offering free shipping to the lower 48 states.

Included with the headers are:
headers
gaskets
test pipes
vband clamps

I offer a 100% money back guarantee if these headers don't make you 40whp or more over stock. They also come with a lifetime warranty.


Price: $2,999 shipped

I so want these man! I am still waiting my pending litigation for a settlement and when I do I will hopefully be getting those! With those installed will I get that sound which I heard on the cls55 that day I was there?

cls55

do have or planningto make headers for ml63?
thanks

stevebez

Hmm mbe I am not done yet...

Plug and play? or is welding required?

and most importantly will it fit a RHD car?

Remind me the diam of the primaries and the downpipe section...

OXOJE55

Great deal

beauphus

why does stuff always go on sale AFTER i buy it? oh well. headers are awesome mikey!!!

Worth the wait

Could you provide a bit more detail as to the install.
I assume this set up eliminates both cats and the second piece connects to the headers via Vband clamp then gets welded in somewhere before the resonators.
Maybe a diagram would help....sorry but I am just not that familiar with all the parts of the E55 exhaust and the specific differences between shorties and Lt's on our cars.
Thanks for the info (and the sale)

I will take some pictures from under the CLS55. This system deletes the primary cats. Secondary cats remain intact.

I will try to get the CLS on the lift today. the system does require a cut of the exhaust pipe. The test pipe then slips over the factory pipe. You can clamp it if you like. I recommend welding it in. once that is done the headers install very easy. The header and test pipe mate together by vband clamps. I find the hardest part is pulling the old gaskets off.

How about fitment on RHD ? and other questions above?

Also what happens to 02 bung / sensor?

TopGun32

any chance of shorty headers??

I know the LT are the best solution.. but it kills me to think the exhaust manifolds are really tiny in this car.

Hammer Down

I know that you most likely have already said this but were those numbers achieved with the secondary cats and stock mufflers in place? and are there O2 bungs in the headers?

MBH motorsports

I've tossed around the idea of a shorty header. A few things held me back.

1) a bunch of good shops make them
2) From what I'd save in material, really would not off-set the total cost by much. After some number crunching, I'm not sure If i could be competitive on the aftermarket, price wise.
3) This might sum it up a bit more I only want to make things I would use on my car. I've ran shorty headers on my AMG, I liked them alot. Now its become one of those "I've moved on" things.

I totally understand why people want a shorty header.

MBH motorsports

Yes, all of our in house testing for the 55k headers have been on cars with the secondary cats installed along with factory AMG mufflers.

The o2 bungs do not require any extension what so ever. You simply install the stock wires back in there respected bungs. Location of the first o2 is on the header, just after the merge collector. The other o2 (or post cat) is located in the supplied test pipe.

I give up...

mikey33

Hey Mike. So if I buy the headers it will come with everything I need as far as piping and deleting resonators and cats and stuff like that or is something else needed to finish the job properly? Where does a x-pipe or h-pipe that I have heard about come into play or does it not? thanks.

jturkel

wicked deal MBH! GL with the sales!

cls55

hooly
again, are planning on making headers for ml63?

reitmeid

Based on this photo of stock exhaust:


I assume you cut the stock pipes just before where they curve to the sec.cats, and slip over the test pipe, right?

MBH motorsports

I'm going to give it hell. Im looking for a ML63 right now. I have a few local guys I'm waiting to hear back from. Its hard to say what the time frame is. If there is anyone with an ML63 willing to come to AZ. I'll make them a smokin deal.

MBH motorsports

The test pipes have mounting tabs that use the stock mounting points beside the bracket, by the transmission.

Worth the wait

Great info...thanks.

How about a tune???? I know it would help, but is it required. Are the gains you experienced without a tune?

MBH motorsports

Totally stock file. I've been asking my brother for some time now about tuning his car. I know when I make the SL55 headers, I'm going to try and make 100whp from a pulley, tune, and headers.

So the tune is not required to see these gains. However deleting the cats will toss a post cat CEL. My bother has been living with that for some time now. I joke with him a lot when I get in his car. I'm like "When the heck are you going to get a tune to shut that cat code off?"

I Like Soup

I was under the impression that with a long tube exhaust install, you will start to run lean, thereby necessitating a tune? Is this not correct?

930chas

Dayummmm! This might be too tempting.

MBH motorsports

Its not a must. I can get the AFR of a few before and after runs. IIRC my brothers AFR adjusted a 1/4 point. From what I've seen of AFR's on stock 55k's they are a bit rich from the factory. so adjusting up .25 of a point is nothing the ECU cant adjust for.

If you where creeping up to the 13's then it would be time to get a tune.
