stock exhaust hitting 8.8 what can I do?

so I'm 75% done with my 8.8 swap, did some quick searches and couldn't find anything since most swaps were on lifted rigs. Mine is all stock suspension, and stock pipes and the tailpipe right at the first upwards bend just out of the muffler is hitting the 8.8 on the flange where the 3 bolt holes are beside the pinion.

I know I could just replace the muffler with something else, which I plan to later as the baffles inside are rattling, but I've been strapped for cash lately and this thing is sucking more and more out of me, plus I have limited time cause of kids and crazy work schedule. At this point I'm thinking I will just let it go and drive it dealing with the banging and rattling for now.

Did anyone else encounter this exhaust issue with the 8.8 swap in their ZJ?

may i ask, why are you doing an 8.8 swap on a stock rig? did your rear end blow up or something?

Cut that flat piece off with a cut off wheel. I thought I was going to have that problem w my 5.9 but mine clears it.

you could cut the pipe after the muffler and throw a short turn down on it. install a new hanger that holds at the turn down.

i haven't done the 8.8 yet but i did modify my exhaust with this trick and it doesn't reach the rear axle.

good luck man

not entirely but yes it was close. the rear was bad when I bought it in october.

It looks stock, but it's not, did a 242 swap, swapped all 3 CV shafts for Ujoint shafts, and had to shorted the rear DS for the 242. All of it was bad when I bout it. Just did most stuff right away to start driving it. I do plan to do a 4.5 LA lift later down the road in a year or 2, so beefing everything now that needs replaced so I don't have to worry about breaking it after I lift it.


Thanks for the tips yall. I think I figured out what I am going to do though, my exhaust is all stock except a Flowtech Terminator muffler that has the stock configuration. Well inside is starting to rattle since it old, so I'll get the same thing again cause I like the sound, but since they are reversable, I'll put it on with the offset as the inlet and the center as the outlet which will pull the pipe away from the axle a couple inches. And to make the inlet match up I'll put a pipe in with 2 bends, like 45* or so that way the pipe will be off to the side of the frame rail so the muffler stays in the same spot.

And the swap is done. Been driving it since sunday nite.

you can also move the exhaust hanger up a bit. i did that to clear it. if you look at your stock hanger rubber gromet thing theres two holes. i jsut put the hanger through the top hole. cleared everything hehe

most mufflers are directional, don't reverse it.

Like I said above, Terminators are reversable.
