Cat/Exhaust/Nutter question

I have an 87 4.2/5sp. PO had removed catalytic converter and exhaust and installed a glass pack. PO also pulled all of the pulse-air system. I did the Nutter bypass and installed a Weber carb.

The glass pack is extremely loud, too loud when driving topless. In addition, the pipe ends right in front of the rear axle, pointing down so I worry about CO gasses. I want to install a normal muffler with an exhaust pipe that comes out the back like it should, and a catalytic converter to be legal.

Question is, would a catalytic converter still work with all of the pulse-air and other stuff disconnected?

Thanks,

i would just throw a cat back on, but to answer your question yes, the cat will work as regardless of whats under the hood, it acts as just a filter for the exahust

I just did a cat back with an el cheapo muffler and stock replacement tailpipe on my 95 2.5. Help us both out and provide some help as to how to get the new tailpipe to fit over axel and rear sway bar. I don't seem to have enough room to get it to fit. Everything else works like a charm.

The trick for getting a stock tail pipe to fit in is to either put it on a lift or you have to jack up the back of the Jeep high enough to let the axle sag on the springs, block the frame, and then put your pipe in. But don't tighten everything down until you get the jeep back on the ground so you can adjust the pipe side to side for clearance.

Easiest way to put it in is from the front drivers side. Start the tail pipe thru to its destination, Sometimes its easier to eliminate the rear drive shaft for more clearance.
