Mac Mids on a 2 cat car???
I have a obd2 car with 2 cats and i want to put the Mac midlength 1 cat headers on. I'm sure people have done this but i couldn't really find good answers while searching. I know i won't have my rear o2 sensors but will my egr and air hook up? Also how should i connect the y-pipe to my slp catback?

What you do is the Single Cat Conversion. I just did the conversion, Steroman did the conversion and several other people have done it.
Here is what you are going to need
93-94 Mac Headers & Y-Pipe
SLP Loudmouth S-Pipe
Carsound Cat 3" or Straight Pipe
1 O2 extension
Send in your PCM to Remove back O2's or O2 Simms
It is way cheaper to order the single cat Macs this way, you will gain more horsepower, and they have the best spark plug access.

Yes, I did the swap. You can search on my name, and the word MAC or mac's
96redformula7 summed it up though.
You can also put a bullet muffler in place of the cat, see my post I made yesterday about it.
