So I bought a Borla XR-1 (40942) muffler with the following specs:

2.5 in. Inlet - Centered
2.5 in. Outlet - Centered
16 in. x 4.5 in. x 7.88 in. Case Size

It looks like I might have effed up because it appears the outlet should be offset according to the diagrams I've looked at. Can the muffler still be installed on my rig? If so, can it be done in my driveway (like I was hoping with the help of youtube vids) or should I take it to a muffler shop? I'm also worried about clearance issues as I still have a 4.5" lift and a ZJ gas tank skid plate to install. Any help is appreciated!

If you want it bad enough anything is possible. The easiest would be to exchange the muffler for the correct one. If not a couple of bends, a welder and a saw and it will fit. Can you do it in your driveway? Depends on your skill level and insanity. When I was young I did a lot of things to my race cars and hotrod that "couldn't be dine" simply because I didn't know it couldn't be done so I did it. Didn't always come out well and often wasn't the best way but damnit I did it.

I can't exchange. It was a private party sale. I checked quadratec and 4wheelparts prior to purchasing and they both considered it a "fit".

I guess I'll have to take it to a muffler shop. Hope it's not too bad.

Really shouldn't be too bad, a couple of bends to line up and a weld or two and you should be fine. Without seeing the muffler and tailpipe it's hard to say for sure but I can think of a couple of ways off the top of my head to line things up.
