picture of my problem exhaust
 

here it is

second one

problem?
 

So whats the problem? it looks great werked 66.

Perspective in a flat picture taken off angle is rough but it looks to me like the H pipe is too narrow and this promotes the passengers side header pipe from being directly along the side of the transmission tunnel. The two pipes should both go down their respective sides of the transmission tunnel leaving the central area free for the driveshaft. Emergency brake lines also go down the center and if not equally spaced right/left I can see why you're having problems.

your exactly correct about the pass side i go in the tunnel way to much got more pics and you can really see it more i ahve been talking to the guys at mac and said if i can show them the problem might be the h-pipe the will send mr a new one let me know what you guys think

more....

and one more

last one so what do you guys think should he send me a new h-pipe

If you reverse the connection at the header reducer flange, what happens to the pipe? I realize this positions the "H" pipe outlet facing away from center but to me it looks like they welded the "H" connector on the wrong side of the pipe. If you reverse connect it, does the pipe line up with the transmission tunnel? This is AFU.

I agree with Jeff65 , looks like the weld is in the wrong placs . Did you preassebbel the parts before yoy installed them? Take them off and try to turn, flip, rotate ect. them to see what the deal is . I would then take the parts and pic to where i bought the kit and let them know what you found.

if you look at the h-pipe there a male and female ends on it it can only go one way but a far as turning it around did that as well last night does not clear the tunnel just as bad if not worse i also spoke to the guy at mac and said to me lookds like you have the wrong h-pipe um duh you didnt have to tell me that i told you that ..... well he said he is gonna show the pics to other people at the shop and if the agree that it is the wrong h-pipe they are gonna send me a new one well unitl next time the saga continues......................... by the way got the whole system from mac isnt it nice they cant even send me the right parts

also thanks for all the input guys i am lucky to have found a web site like this with this much info

You're not the first to get wrong parts from a vender, and will not be the last. Question is how are they handling the problem.
