I was looking to replace my mid pipe . What's the advantages of using the TJ pipe ?
Advantage of the TJ mid pipe?

I have not used one, but my understanding is it wraps the pipe around the front of the oil pan and then basically straight back to the rear connection. I don't know that there's truly and "advantage" to using it per se.
I could see there being less heat on the rear main seal with the tailpipe not running under it, but that's sits on the block, gets pretty hot there anyhow. So, maybe someone else will chime in with what benefits they saw.

I did it.
It was one of the 1st things I did, put a new exhaust on it.
It was for clearance mostly.

From a performance standpoint, it changes direction about 5 times. It's a pretty convoluted design.
If I were to use that pipe, it would have to be wrapped. I don't want my oil pan surrounded by a pipe that can reach 900+ degrees.
The standard pipe sucks too. But from a performance perspective, it sucks a little less.
My stock pipe has been smashed so many times it no longer hangs down.
I'm sure all the dents in it aren't helping engine performance either!
I'd like to build my own that crosses sides... Maybe over the front of the read drive shaft... I don't know.
I do know both the YJ and TJ pipes each suck in their own way.

Just route it straight up. M35 snorkel on one side, exhaust stack on the other!
The idea of it allowing more clearance is attractive, and why I am doing to to the project jeep.
It also lets you 'hang' the front pipe from the engine/tranny/tcase and then put in a flexible length ahead of straight pipe slightly more easily if you don't have or don't duplicate the stock pipe hanger. I don't think the multiple bends are really a big deal at our flow/performance level, though I'm also of the opinion it does have some negative effects.

I don't like how that 900* pipe almost completely encircles the oil pan.
I can just imagine the prius drivers faces when they see that lol
...pretty sure AMC/chrysler referred to their YJ configuration as the 'rear main seal sensor'.
I can see its advantage and disadvantage ( and agree with Chris ). But if you intend on a flat belly skid (as i do), you can see an advantage to running one as it allows you clearance and length to gradually bring your pipe up and tucked away neatly without drastic/awkward bends.
I'm running headers (long tube design)... it connects to my mid pipe quite low. Not too sure i can go the TJ route for my belly up. But yea, if u do... it would certainly be an easier and more natural looking design.

If you hit your tail pipe on rocks a lot, maybe take a look at your driving habits. If you are comfortable with bouncing your underside off rocks all the time, then try a TJ pipe if you'd like.
Otherwise, leave it stock. It's like $20 for a stock replacement. And if you are replacing it a lot, the bolts will be real easy to remove

That's because the keep getting rolled with coal by smoke stacks at every stop sign... Then constantly need to stop immediately at a car wash otherwise they can't see out the windshield. lol. BTW, I'm firmly in the camp of passing a law to immediately execute all coal rollers via scrotum sized guillotine...

I also did some work on the tail pipe. Placing it up into the body more and not having it hang down in the "bash zone".
Photo bucket is copping a 'tude right now, so I can not post pics...As soon as pb and me are friends again, pics will happen.

Don't think that'll happen anytime soon... why not post direct here...
And FWIW, i run a TJ pipe, for clearance...
I dumped my exhaust after the muffler and brfore the rear axle

Better ground clearance than the stock pipe. Not having to loop under the bellhousing/oil pan helps keep things up and out of the way of things that like it hit it.
When I installed mine, I wrapped it in heat insulating wrap to help cut down on the heat in the oil pan. That one small negative does not outweigh the good.

You don't mention any issues you are having with the current setup. Why are you considering replacing it? By altering the routing, what actual problem you have are hoping to fix?

It has holes from being patched over and over. I was looking at the magnflow tj pipe with the converter. I also need a converter.You don't mention any issues you are having with the current setup.

Why? It will have no effect. Those who do this are already impotent and may be compensating for small... or otherwise poor self imagemike134 said:

I'm only doing it to help me execute a flat skid. Actual numbers not yet known, but my motor/trans/tcase appear that they're going to be 2" or so above stock if I don't have to beat the tunnel too much. As far as the heat concerns, one could wrap the pipe, but the manufacturer didn't seem awful concerned with the TJ when they built it?
Further, with the addition of a short flex pipe, I'm thinking this little extra length will let me hard mount the cat and back without constantly breaking the front hanger (oem front hanger is on the trans mount.)
