Anyone have any fitment problems with unequal length mac shorties? how close are they to the stock engine mounts?
Thanks in advance
These is on my Coupe but I thought it to be relevant. I had a set and they lasted for about four years and then I started having gasket issues. They would blow out between the head and the header . I went through all kings of trying to keep them sealed up. Pulled them off and they were warped so I chucked them in the recycle bin and installed some BBK shorties. They have been on the car for over seven years and no issues what so ever. The from the header to the head is much thicker than the MAC units were and the quality was a bit better IMO.

From what I've heard MAC headers are just bad. They tend to warp because they don't have a that links all of the tubes together...
Its been a few years since I had them and thunderjet302 is 100% correct. I had gladly forgotten about how they lacked a one piece . It took a small pry bar to get the tubes to line up so you could bolt them up to the head towards the end of their lives. I think I just relived a nightmare...those things sucked. The BBK headers I have now are one piece and I have had no leaks.

I had that same issue. Fit great at first, but got worse with each removal/installation. I cross-threaded many a header bolt with those bad boys, attempting to pry them back to their original locations.
If you must have a set, I recommend getting studs. They made life worth living after fooling around with those headers...
Thanks guys, I am now convinced NOT to get them!!....... they were a fairly good deal but I am going to pass.
