New MHP Gen 2 headers in.
Wanted to eliminate the slip fit in chasing a leak. I would have liked to try the MBH but I never got a response.

Im curious to see if Ill get anymore power out of these from the increase in collector size.
I have my track data from last season and Ill compare that to next years with these new ones on.
Heres a pic.

I think its with the blower cars where it is POSSIBLY an issue.
I am not even convinced mine was leaking, but I am just trying to eliminate things.
modular exhaust manifolds arent even that bad to start with design wise (not talking installation lol). ford doesnt leave nearly as much on the table as the other brands. most brand's stock manifolds are like logs, cast and horribly restrictive. I dont think the 63 headers are all that bad depends on what car and which brand. Theres definately easier out there and harder too.
good luck
Want me to get my bro to weld you an X pipe, it will tone that ugly raspy and crackling noise down and smooth out the flow.
I dont know if It was in my head, but I felt a bit more mid range after the X pipe was installed.
I have my old mids off so I can shoot him the dimensions easy... pm me if interested.
Tried to get a hold of the guy no answer.
These will do just fine. I think the larger collector will help power a bit.
Honestly I love the sound of mhp with an X pipe.. The mbh sound different.
My friend Blowin63 with the weistec stg 3 just went from mhp with no x pipe to mbh with an x pipe and he only gain 15 or so Rwhp. Dunno how much affect the x pipe has...

Also re-using the MLS header gaskets worked fine, not even a hint of leaks!! I'm pumped and wanna drive it!!!
