For you guys that run a MAC Pro Chamber with factory manifolds ( PC9994 ) can you tell me how your Pro Chamber sits after it's bolted into place please ? Is the pro Chamber " box" part itself angled towards the drivers side at all ? Not the whole box itself but angled towards the drivers rear wheel ?

I got my pro Chamber mid pipe kit , installed my new down tubes off the exhaust and left them a little loose till final mock up with the pro Chamber in place , and when I bolted the chamber up it angles itself towards the left rear wheel a bit . So I send it back to MAC and they put it in their jig and send me photos back saying there is nothing wrong with it . Are the fitment of these things that bad ?

Note I am 110% certain I have everything installed correctly. The Chamber is not upside down or anything. Thank you

I'm trying to picture how its angled differently but I just can't, mind posting some pics? There is really only one way to install these, and mine sits flush not angled/turned or anything in any direction. I can give you some pics if you want, but lets see what you're working with.

i have read some accounts that the driver's side manifold studs must be changed out for the type without the shoulder (same kind as on the passenger side) with the prochamber.

i don't know this for certain, but i believe there are some posts that allude to this. on the other hand, there are many folks have said theirs fit fine with no problems.

does the connection at the d/s manifold look good?

I replaced both studs with continuous threads on manifolds ( no flange) before I dropped the motor back in . The ball flange is tight against the manifold
