First I want to say thanks to Mike from MBH. He took his time to answer all of my many questions and the whole experience with purchasing could not have been better. I purchased LTH/high flow cats/test pipes/midpipes/xpipes (basically every option). Everything shipped 3 weeks after the order was placed and Mike was available and answered all calls during this time. Received a tracking number as soon as the package shipped. Hid it in the closet from the fiance for a week after . Finally told her about the box and she was ok with it lol. Everything was packaged extremely well!!! Anyways here are the unboxing pics...leaving the bubble wrap on to make it easier to transport for install (Unless I can't sleep tonight and do a full unwrap.) Plan on getting a before and after dyno w/ an updated LTH tune from OE. Will update with more pics/video when I get to the shop!!!
Does anyone know the part numbers for the bolts and gaskets? I want to order these before I go for the install. Ok on to the pics!!!
Nice. You wont regret it. Now only if mike would respond w more urgency.....
The best way to get a hold of me is to call. If that fails for sure leave a message and I will get back asap. I am human though and if I forget. So feel free to call me back
Gents - combining a 3" exhaust system up to the backboxes/rear mufflers....dyno proven to make more power and torque, than just slapping the longtubes on and mating them to the stock oval piping/resonators?
I know it should make more power, but seeing as the resonators are straight through and the majority of the gains are from the longtubes/decat combo...i'm wondering if it's worth going the whole hog and having stainless steel piping all the way back?

You might want the studs as well. Last install I did every stud turned out of the heads with the nuts except one. Rather than try to hold them in vise grips or something and marring the studs to get the nuts off I just replaced them.
These headers are INCREDIBLE!! The quality and craftsmanship is amazing!!! Looking at the welds, the design, the material. I cannot say enough how blown away I was when unwrapped these headers. Mike I have to say thank you for putting out such a high quality product!!!! Pictures/videos do not do this piece justice. I've seen pictures of headers from other companies...I'll just let you guys come to you own decision....
Well made? They look OK, but some of the joints are mismatched and there appears to be a few miter joints which even though it doesn't hurt performance much, it just doesn't look good.

Please explain what you mean by mismatched? Are you referring to the stepped design from primary to collector? As for joints, anyone familiar with bending tubing will tell you, you cant have 2 bends compounded on the same section of tubing without a minimum straight section in between bends, usually that is 4-6 inches. Consider the space limitations for the car... We think we are doing a kickass job of making an extremely well performing, and built header with barely enough space left to fit your hand.

Yes there is one tube that looks mismatched going into the Y. The other tubes going into the Y don't look this way. As far as the miter joint, maybe it's necessary for your tri-y design but I'm just not used to seeing miter joints on headers. The good news is a Hot Rod video where they dented the heck out of headers and never showed a power loss so I'm sure your miter joints are fine.
And I will give you credit for using the tri-y design. I think NASCAR has proven it is the best design for big V8's.
Guys, no need to be defensive. I love the tri-y design. I think these are the best headers for the C63. But from a quality standpoint I think the ARH headers are better by just a bit. But I'd still go with these from a performance standpoint.
