bad 430 the dyno thing is really a tough call.. i know where your coming from, but he's probably better running down the 1/4 and seeing what MPH he traps.
I dynoed my GTR at 4 different events within the same month and pretty much same conditions for the most part. + or - 10 degrees. and my car showed 1030 on one dyno and as much as 1280 on the other dyno.. but i know trapping 163 with the car is much easier to get an all around whp figure

In fairness, I didn't think either side was worse that the other to it's counterparty. I also I don't see why Shell was banned either. Isn't it supposed to be a free country? Even if people think he is full of it, etc.?
I don't own either brand of header and to be honest, it shouldn't matter if I did.

^^ no worries Mark, you are welcomed to post your feedbacks/reviews on your mods... it's just that when MHP name comes up, people gets bitter for what they have done to other members in the past (mostly the bad)... LOL

No I haven't, dyno's dont mean much to me, you see plenty of cars on here with their dyno sheets, same car, same mods and the numbers are all over the place. I remember I had my car dyno'd once when it had just a Renntech tune, it was extremely low. Not sure if it was the dyno or what... But they had a file from a stock SL63 and I was 2hp under what he put down so that made me happy. Since that experience, ive never cared to go back.
I like to spend my time at the race track, where you can talk dyno numbers all day long till your blue in the face, but the little yellow light at the finish line doesn't lie.
I just want to be clear, Im not defending MHP or anyone. I state my experiences with the vendors and parts that I use as candidly as I can.
Im not trying to be a *****, but Ive spoke to you before regarding the mhp vs mhb headers and you said you gained 40rwhp hp. That's very misleading, especially now that other guys are spewing it out and forgetting these minor details.. You didn't mention this back then which is why Im so surprised now because the leak and added X pipe is a game changer in my mind. I specifically asked Weistec if I should switch because of our convo and they said no, mhp headers are fine, just make sure your collectors doen't leak.

my car is for sale so nobody will be seeing any videos or numbers coming from this car until the new owner drives it like it should have been driven
no hard feelings Merc63 . i'm not here to make enemies
it's time for me to move on to something quicker and make more power

Absolutely, why would he not pass on the 100% non return rate? Did you miss the post in which I stated I talk to him nearly every day?
You post pics showing shipping damage, and that's something that should have been brought to MHPs or the shippers attention (now I'm not sure if thats fedex or ups so you got me there). Either way it wasn't brought to my attention.
If you want to lay your cards out and have an open discussion you'd let me repost your website pics here Mike. Obviously you don't want to play fair and that's your decision to make. The site will see the numbers from its peers and at least one vendor, potentially more now, in the coming weeks. Maybe they will take pics of your headers to post in comparison, hopefully you won't object to it as MHP has not (so we're clear Andy told me he doesn't care what you post, via text about 30 min ago).
I'm sorry you dismiss someone posting factual info about a product as an "attack". If everyone did that Lord only knows where we would be as a society, probably still using horse and buggies.
See you in the am.

I just added a used set of 1st gen MHP headers and an OE stage 2 tune, picked up 45 RWHP and 43RWTQ over my stage 1 OE tune. Car is loud as hell but the power is amazing. MHP may have some sketchy business practices according to most, I personally have never done any business with them, so all I can say is that there headers work and work great. I would recommend them to others.
