For those of you who are running the lowers triangulated, what did you do with the cat when you put the rear x-member in. I'm gonna run a full belly pan & unless I build in a 3" drop for the rear x-member, the cat HAS to go. This isn't a big deal, except in Pennsylvania to get the state inspection done I need it. Any pics would be appreciated.

You're going to need to do one of a couple of things:
1) get a narrow tube-style cat like in Jegs and run between the x-members.
Example: http://www.jegs.com/cgi-bin/ncommerce3/ProductDisplay?prrfnbr=192834&prmenbr=361
2) mount the cat in front of the front x-member (before the hanger)
3) run no cat and get an O2 simulator.
4) run no cat and cross your fingers that you don't get a check engine light. (That's what I ended up doing - cause I'm a lucky sumbitch)

The muffler is a real bitch too. Best options there are either a glasspack or some other tube style muffler (no larger than 3.5" - 4.5" in diameter)

I didn't have to do anything with the CAT. It was fine where it was at. I did however get a flowmaster that was only 5" wide and 24.5" long, so it would work with my new x member. I am all fucked up now, how do I attach a pic now.
