ok i so plan to run a trush glass pack. and i need to know what am i going to need and what diameter glass pack i need to get it to match up to the stock cat. my cat ? i want to clamp it on even tho welding would be better.
this will be the first time i ever do work under my jeep so need some guidence

the glass pack will need to be a 2 1/4" I.D. inlet i think. that should slide right over your old exuast

alright. from there do i need to put anything on the end like a pipe ? or just cat then glasspack ?

I would just take off everything behind the cat and weld the muffler on and a turn down

From recent personal experience i would not go with this. Sounds horrible and cabin drone is insane. I wouldnt run any muffler turned down under an xj. I would say if u want the @sspack get a muffler shop to install the tail section for you. You will thank me later!

I would recommend a 2-1/4" center inlet with 2-1/4" offset outlet. OEM length is close to 25" so a shorter muffler will work with the addition of a section of 2-1/4" pipe. Relpace the old muffler with the new, re-use or replace the tailpipe with an OEM type that keeps it up high and tucked in between the leaf springs and fuel tank. Clamps work fine.

I cut the turndown end off of my tailpipe and replaced it with a straight piece that exits beyond the bumper and it cut down on the droning.

well.. what would u recomend? and just take the muffler into a muffler shop and ask them hey put this on and can you add a tail section? that dumps out underneath the bumper?

I bought a 23" CherryBomb Glass Pack and put that on after the cat. I left it just like that with no tail pipe. It was crazy loud, didn't sound all that great and droned like hell. I then cut the OEM tailpipe off the OEM muffler and got that on there. Now, it sounds awesome! I get compliments all the time and have even been asked on multiple ocassions if there is a Cummins under the hood.

i plan on doing that...but im sure you had to go out and buy new hangers right? bc it shorted it up or no? it hooks right up to the factory mounts on the tail pipe....if it helps im going to het the one form summet raceing...

Your gonna need new clamps for sure. Hangers, no. Atleast I didn't. The front hanger on the tail pipe won't really bolt up because the glasspack is straight through while the OEM muffler center in offset out. The rear hanger is just a clamp.

gotcha. how long is your glass pack? jw i think the one i am ordering in nov. is like 23in some where around there maybe more
