exhaust.. is duel exhaust a viable option?

Ok... So I have '94 XJ sport and I was wondering if true duel exhaust on an XJ is a viable option that won't cause you to lose back pressure.. Because from my research a 96 XJ has split headers that will bolt straight into a 94 block. And that option would leave the only challenge to be the route of running the pipe..I am talking about the 4.0 HO inline Ofcourse...

Honestly other than maybe a bit of cool factor there wouldnt be much benefit to doing it. I mean anything is possible. It all depends on how bad you want to get it done. Lay under the vehicle and take a look, try to look where the routing would go and what you would have to work around to do it.

If it were me I would want some type of crossover or x-pipe in there to equalize the exhaust on each side. That alone can create some space and routing issues, especially on a 4wd (front drive shaft, t-case and trans clearance to think about).

I don't see a big performance advantage unless you have a hopped up 6 cylinder. You could get a nice performance gain just from bumping up the size of the single exhaust and adding a good flowing muffler. Which brings up another option, you can route your exhaust into a single in, dual out and then have a dual setup that way.

If you really want true duals, you can do it, just get creative.

If it wont go...force it.

I work in a muffler shop building duels and I also just bought my first jeep I was thinking about doing duels since it will cost next to nothing but personally for the price people get charged to have a pair of duels put on I think your better off with a straight through design muffler and getting rid of the cat unless you have the o2 behind it on your model much cheaper same performance but I'll let you know how mine goes when I do it
