broken d28 front axle, and exhaust question

[bronco2dude]

I have a b2 that I recently bought, I didn't realize till I got stuck that the 4x4 didn't work so I looked at the axle and discovered that the passenger side axle shaft was broken at the u joint. The hub side is ok from the looks of things I looked and found another u joint farther up next to the pumpkin, and I was wondering if I can take it off here? Or do I have to pull the pumpkin apart? My second q , has anyone ran true duals off of the h pipe? I don't have emissions and the person before me broomsticked the cat anyway. I had to remove it and the reast of the exhaust because it was jerry rigged. I will try and load pics, I have a photobucket can't figure it out.lol thx for the help.

here is my exhaust if it works.

just run a set of pipes off each of the outlets you have after the h-pipe, put a universal cat on each of them, and then you can run duals all the way back, it'll work like a champ.

That's what I was planning on, I just couldn't find anyone else who had done it, but minus the cats. Lol where I live 25 years old is the cut off for emissions. Lol but thx just the advice I needed.

yeah, but your engine WILL run better with some after market universal high flow cats, for serious.

failing that, run mufflers with a little more backpressure, but your engine is tuned for cats, so unless you retune it there will be no advantage to being catless.

Totally. If you ditch the cats and just run straight pipe and a normal muffler, your back pressure will be all screwed up and you engine will run worse, not better.

O, lol never thought of that. My cat was already gutted out, that's where I got the idea to just run catless. I like the louder sound anyway. but does anyone have any ideas for taking out the front axle shaft? I looked at the tech library but I couldn't get it.
