MHP question...
Hope we keep it civil & not let Shell close this thread.
Hope we keep it civil & not let Shell close this thread.

If I found something or had an idea that I thought would be better then what we have now. I'd do it. I would not hesitate to bring it to market. Are there tweaks we can make to our current headers? yes. The tweaks I'd like to make would only make building the headers a bit easier. Rather than shaping each round tube to mate to an oval port. This would save is a bunch of time in the building process. However it would cost a boat load more due to machining costs. In turn adding to the over all cost of the header.
in retrospect, If i was doing it again and making money was a top priority... I'd make a 4 into 1 header for the 63's. Only because it's the cheaper to make, and people have a vision in their head that, that is what a header looks like. Or event to be a long tube header the collector HAS TO sit under the chassis. If that was the case our S55/CL55 and G55 headers would be 8 feet long.
The fact of the matter is the only things you can do with a 4 into 1 is the size of the collector, put a merge spike in the collector ( we do that on ALL of our 4 into 1 headers) And/or make it equal length. I know I'm leaving a few things out, but you get the point.
With a Tri-Y you got a bunch of options you can do. Like how you stage the Y's and Tubing size transitions. Size and length of primaries, length of the 3 Y collectors. The list goes on.
Really though this is a Mercedes and not a 68 Chevy. We've got a lot of things to clear and avoid. Not to mention o2 sensors. People who've had a leak on a o2 equipped car, running slip fit collectors, know that CEL is nothing to mess around with. Since it controls the fueling of your car.
Keep in mind the design doesn't always make one style better than an other. Its craftsmanship and materials. For the C63 I know who's headers are made in the USA. What ones crack, who uses 18 gauge steel and who used 16 gauge steel. For those who don't know, You want 16 gauge stainless steel.
We use 16 gauge stainless.
Here is a picture of a popular Mercedes long tube header using 18 gauge stainless steel.

The guy offered a legit deal with real proofs. Either use your uber money that you like so much to show us , either admit you accused without any proofs.
( regarding the SLS' owners name )
At the end of the day , you only accused without any proofs..... All your blabla has nothing behind it... And that is valid for both parties !
If anyone has proofs , please post !! That would help the thread instead of these little dad's money guys with their big mouths.
If you want the thread to stay civile , stop accusing and use proofs. End.

What a waste of bandwidth.
The Best of Mercedes & AMG
There is this talk that for NA and SC application one is better than the other. I simply dont take it.
I have seen and driven both. The MBH applications pull harder and stronger for both SC and NA applications
Please reply to my PM . It is urgent
That was perhaps the best post of this thread
Let justice or life itself take care of those dishonest ppl.. And we should just enjoy our beloved cars!!
You also lied about how much Mark paid for his headers, no one has ever been charged more than list price for them directly from MHP as Mark bought them. Less in a package. And you would have no clue how much the cams cost MHP to make but had no problem lying to Mark about that or this forum.
Either way the buckets and bolts are en route to the same place Marks cams have been sitting for months, the same place Mark told Andy he wanted to have them installed and had no issue waiting on Dan to get his car out of the body shop so they could both be tuned on site at the same time to save on costs. Im repeating myself now. I applaud Andy for not dealing with customers or shops like you or Mark, I wouldn't either.

I will reopen the thread if requested by the OP or if I'm informed of new developments.
Now everyone go hug somebody and enjoy the day.
As you all might remember who are following this thread, it was originally started to gain an understanding about MHP and their current business status so we could figure out why all the excuses From Andy have all come up empty. Andy even went so far as to another voice, that of "Shell" to assure is that he sent the cams and all related parts needed for the installation. He sent the cams to a third party, stated he sent the rest of the parts and failed to provide all components needed. Mind you all... this has taken a year to produce the parts.
We trailered the car to Critz Mercedes in Savannah for the cams install and documented such on our Facebook page. We found many problems and thank goodness for all the incredible help from Critz. The cams as delivered would have never worked, the bore machining was too large for the stock sized oil galley plugs to fit, so an additional cost for the machining to fit the sized up plugs was necessary.
We had to purchase an additional $2000.00 in parts with a labor cost over $1500.00 to complete the surgery needed.
We are now at TopSpeed Motorsports and made to pulls to gain info on the tune, both which are posted on our Facebook and the video is on the RaceShotsResource YouTube channel. The tune is a joke with no 100% throttle until over 4500 rpm even when the pedal is floored. Additionally the ECU was NEVER RESEALED by Andy which might be why so many people are having such failures after his tuning.
Hope this update helps!
Sorry to hear you have encountered more obstacles with MHP, I am sure Andy or ShellURT will have a good excuse for you lol. Good luck and let us know when that monster is running.

YES, I know the log-file shows 80% when the throttle are open to 100. I was simply sharing that when we are done, it will be different all around.
Here is the link to the video I snapped of the baseline dyno pull. Enjoy the LOUDNESS!!

Thanks for the update, I hope you get this all resolved.
