adding 3" cats to my TD's ?'s inside Hey guys I'm currently running a set of Pacesetter LT's (!AIR, and !EGR), into an X-pipe, bullets, dumps. I am wanting to cut down on the rasp and the smell, so I have decided to go ahead and put in some hi-flow cats. Will I have to re-install the AIR system, if I Install the cats? I really do not want to. Also, what will I need to change in the VCM as far as COT is concerned? I'll be setting everything up on a flange type system for quick disconnect at the track. I think that's it.

Dont worry about the AIR system... Its only there to cut down on startup emissions. I ran long tube headers into 3" carsound / magnaflow cats into a dumped X pipe setup for almost 20K before finally hollowing out the cats and running the duals out the back. I had no problems at all. Keep COT disabled, just keep an eye on things. If you melt down a cat, theyre cheap enough to replace.
