I currently have TTM/ARH LTH's on my E63 and so far I'm liking it except for the CEL codes..
I can really feel the performance gain, and the sound is sweet!
I will try to get a dyno done this weekend to see what the numbers.
I might be a bit biased
but there is NO COMPARISON if you are looking for the ultimate long tube, direct bolt-in system for highly modified E/CLS55's.Pricing will be less than $3000 for THE COMPLETE SYSTEM without cats and an additional $200 to add cats. Some members have already received group buy pricing.
I do my best to bring the best products and solutions to the Mercedes Benz industry and you guys make it all worthwhile!!


True long tubes headers: TTM/ARH, Supersprint, Floored Fab and Eurocharged(very similar design as the Supersprint).
Mid-length: MBH and Kleemann.
All of these systems make great power compared to the highly restrictive stock manifolds but, for the most highly modified cars, there really is only 1 option.

Get a Quaife if you don't have one yet and buy some stock in the tire company of your choice!
The Best of Mercedes & AMG
Fact is, the said headers widely and openly uses 18 gauge stainless steel across multiple platforms that make. We use 16 gauge tubing that has better heat retention across the board, and we use it on every header system we make.
In fact our power gains shown across many platforms has led to MBH offering a 100% money back guarantee if you don't make the power we claim. Maybe I'm crazy, for putting my money where my mouth is, but we are the ONLY header maker to offer that for the Mercedes community. We are also the first (that I know of) here at MBworld to offer an lifetime warranty on our headers.
When you are on top and devote just about every waking minute to headers for Mercedes, There are people going to try to knock you down, with claims of latest and greatest. I for one am to old to get into any who is better than who, but the facts are there, You can buy on theory or you can buy on proven results on the Mercedes.
Our goal isn't to mass produce headers and play a financial numbers game on how many headers I can pump out for a type of car. A smart shopper should be able to see through the puffery in advertising of a new product vs the documented, tested, and proven

Hello Bruce,
I was wondering about the 1-7/8 primaries being too big on the 55's and causing the low end TQ to drop-off a bit too much? I'm sure you compared building these LT's with the smaller standard size LT primarys and I'd love to know what the difference is by going to the 1-7/8?? Your input is greatly appreciated!
Also a one piece primary tube is definitely preferred over sectioned together "j"s and "u"s.
The MBH look fantastic for what they are, a hand fabricated header.

In a nutshell it works like this. Smaller diameter tubes increase exhaust velocity. The increased exhaust velocity will give you torque gains. Where as air in and air out (volume) will give you horsepower. knowing that we wanted to still pick up some torque with these headers, because who doesn't love torque?
To get some of the torque lost with a 330 cubic inch engine with a 1.75" primary (thats on the upper end of ideal) We choked down the the tube leading to the main exhaust system for only a few inches. This resulted in picking up an extra 45wtq and over 45+whp
In fact, when we tested our header system on an all ready built E55. That had Throttle body, pulley, tune, cooling, and shorty headers. we were able to make that car an additional 50 wheel horsepower and way more torque without doing anything else. All this on a Dyno Dynamics dyno. Today with a race fuel tune (100 oct) that car is slapping down close to 600whp on the stock fuel system. I don't even know what it would do if the customer wanted to toss better injectors in it. You can see that link here with the specs and charts.

But primary length and equal length have a lot of effect on any header set. You could make two sets of headers with the same design and primary diameter and change the length of a couple tubes and end up with some very different power levels. If exhaust gases are colliding in the collector instead of timed to scavenge.
I have installed and looked at the ARH and MHP headers for the 63 motors. And Kleemann and supersprint headers for the 55k and a few others. I have not seen the MBH personally yet but get the feeling that Mike is focussed on the right things from what I have read. So far none of them are really fantastic in my opinion. Supersprints are the nicest I have seen. They are all good and make power but not off the charts beautiful and due to physical restraints not anywhere near equal length. In fact way off. I have built headers and know this is very hard to do and to have a price point that any of you would buy in at is probably not going to happen.
As the saying goes you get what you pay for. And there is nothing wrong with welded primary pipes if it is done correctly.

I could not imagine an E85 or race gas toooon.
I have no doubt that the TTM/ARH headers are amazing otherwise Bruce wouldn't waist his time so whether you chose TTM or MBH I'm positive that you will be happier than a kid at Disneyland.
So here is what I plan on doing to my beast:
180-185 pulley range
ported heads & cam (down the road when my warranty runs out)
90mm tb
custom intake
massive cooling mods
What are the thoughts on this setup with the 1 7/8 primarys and 3'' merge collector?
Here is what I have now:
MBH LT's with 1 3/4 primarys and a 2.5'' merge collector that flairs out to 3'' and a full 3'' exhaust with X-pipe, no cats. Here's my concern, I raced two different AMG's that had WAY MORE mods then I did and they both had custom LT's with 1 7/8 primarys and full 3'' merge collectors and I pulled on both of them (the cars had sat for a few hours and cooled equal time, so no heat soak excuses) several times on a highway runs from 30-140mph?!?! So now I don't know what to think, I do not want to spend money to step backwards... Should I just keep the system the way it is or do you all think I should go bigger based on what my future plans are??
