I was just wondering if anyone else has had a problem withthe Y pipe fitting right. Mine seems to be a few degrees off on the driver side. I'm sure we will be able to make it work but I thought these things lined up perfectly.

 

No problem at all with mine lining up. My only concerns were that my #5 header tube is hitting my steering shaft...but that's because of weak motor mounts, and on my'93, the heat shield on my oil pressure sender is resting on the header. They've been on for a year, and it hasn't created any problems yet.

What about the weld on cat flange? Did anyone have to cut it b4 they welded it?

 

My set-up is a little bit "custom". The nice thing about the MAC headers is, you can still run a catalytic converter for emissions reasons. Because of this, I have 2 pipes for my car that I can interchange in a matter of about 20 minutes. Both pipes are flanged identically on each end. One has my high flow catalytic converter in it, and the other is my MAC off-road pipe with my cut-out in it. I did have to do a little cutting on my cat, but it's a universal fit unit. I'm not sure how it will work with the stock converter.

We finally got it to line up but it took alot of pushing and pulling. Also the o2 bung on the driver side had a peice of the interior piping in the way of the o2 sensor! So I had to grind the freakin thing out!! I guess I got the crappiest set of MACs ever made!
