I put a set of MAC headers on my '93 Z a few months ago. The MAC AIR fittings are pipe thread. My AIR tubes are flared. My AIR tubes just slide up and down in my headers, and have a pretty big exhaust leak at both of them.

I e-mailed MAC to see if I was supposed to get adapters with my headers, but I haven't got any response. Has anyone else had this problem? Was I supposed to get adapters to go from flare to pipe?

You were supposed to cap the headers and do an !AIR SLP is the same BS and you have to buy their install kit. I don't know if your macs where supposed to come with them or not, sorry.
