Muffler size?

Hey I'm about to get a muffler and put that sucker on my 93. How do you determine the size of the muffler you need (showing my inexperience here). I would like to do it myself, but I want to make sure I get the right size. What else will I need other than the flowmaster offroad with the right size? Should I just leave it without a pipe and drop it? Any help would be great!

well that depends on the size of exhaust you have right now, most are going to be 2.25" that will most likely work, are you going to weld it up? otherwise you will need muffler clamps. you may need a sawzall, but most likely a good beating hammer to remove your old muffler. after that its a matter of beating on your new muffler and clamping it down.

I just have the stock in there right now. I don't plan on welding, I can see catastrophe there. I can get a sawzall but I'm pretty good at putting alot of pissed-off behind a hammer. So once i clamp the new muffler to the old pipe coming from the motor, I can just leave the exiting hole the way it is?

For example, should I leave the tail pipe or dump it? Is the stock exhaust pipe ok to clamp and leave it?

oh the choice is up to you, you can get a cool sound having no tailpipe, but the tailpipe will direct gasses away from the undercarriage, so that it doesn't smell when idling .

Ok thanks Luke. Should I leave my exhaust pipe to the muffler the same or should I change it?

2.25" does just fine.

If you plan on running a tail pipe, the XJ type will be center in and offset out. That should give you close enough to stock to still use the factory hanger locations without issue.

If you intend to ditch the tailpipe, you may want to dump it out the side instead of letting it out underneath, my $.02

Awesome! Thanks everyone. I'll probably buy the super offroad FM, clamps, and turndown tip and see how it sounds!
