    Well I had some trouble in the past with routing the exhaust on my Jeep because I have a PTO driven winch. I got it to work but it is really poorly done. I would just like to clean it up and make it look alot better than it is. You can see in the picture part of the original pipe that was on it when I bought it. I found a page that has a white CJ5 named Tonka that has pictures of exhaust routing for a Rhino PTO. I would like to know what the factory exhaust pipe size is. I'm going to have to buy the factory down pipe from the manifold. and go from there.

    Original OEM winch instructions call for the stock front down-pipe to be simply slightly bent sideways and downward, and extended a few inches, to pass under the frame cross member.

    See attached Koenig manual.

    In your final picture it would be a straight-line shot, instead of the hump over the crossmember. Easy-peasey.

    It's easier under the cross member, until you have to drop the cross member, then it becomes become hard. :( The original winch install kits came with a piece of flexible pipe to go under the cross member but I hate that stuff with a passion.

    The exhaust shop actually screwed this up a bit, they dropped the pipe way too much behind the cross member, it should have stayed up higher within the frame- up above the end of the PTO but they said that were concerned about it being too close to the floor (stock runs up higher). I might get around to fixing that someday.

    The pipe is stock sized 1/5", they said they could have run 2" without an issue. The pipe from the manifold is formed an inch or towards the frame from where the stock pipe would come down.

    I went with stainless 'cause I also hate rust with a passion :D

    Would that be 1-½"? Or 1-¾"? I forget right now and it's too cold to go measure.


    The flex pipe is not even legal some places. But if the OEM pipe is tweaked slightly, a short ridgid extension piece will fill the gap.

    Could be 1 3/4", I might be wrong. I't the same size as the old one whatever that was.

    When I originally bought my 59 cj5 it had a pto winch and the original exhaust was nicely bent out of the way and passed under the tranny crossmember. So I wouldn't cut up the toe board of the body to pass through there since it is not necessary

    Well I found a original Koenig PTO hanger bearing. I went to put it on and it hits the exhaust it looks like the exhaust is going under the cross member now. pto 1.JPG pto 2.JPG

    [​IMG] I use a lot of stainless flex joints (common on front wheel drive cars) when making exhaust Nickerson makes them in many different sizes. You could run one where the pipe needs to go under the cross member. They have helped with donut gasket lifespan and header leaks by allowing the pipe to move independently of the drivetrain.

    I'd want to check on the legality of those. IIRC my state DMV used to prohibit flex pipe unless to the rear of the passenger space. Probably the modern type you show is more durable.

    I routed mine this way before I knew to go under the crossmember. Exhaust shop bent this for me to go over the top. I still have at least 1/4" clearance from all the other stuff in there. It's a tight fit but doesn't interfere with the steering or PTO shaft. That was how I found it with the old exhaust form the PO. Winch was installed at the dealer.

    they are factory on every front wheel drive vehicle to allow the engine to move. they are three layers thick two mesh stainless and one coiled stainless.the one i showed is just a weld in replacement so as not to have to replace the whole pipe.

    Sure. But some inspectors frown on exhaust modifications.

    Ok that's the same one I have except mine is a single output. Is the exhaust 1-1/2 or 1-3/4?
