Exhaust Pipe size and new muffler help

I have searched and it may be that I am not a good searcher, but I cannot find the exact measurements for the exhaust pipe.

Here is the deal. I am looking to buy a new muffler for the 00' XJ. I am looking at the Thrush Welded series and there are quite a few choices to make here.

First off, what size inlet and outlet tubing do i need on it: 2.25" or 2.5" to mount up to stock tubing? Also do I need center inlet and offset outlet or center all around. I am not in a good position to get under there to see, so please help me out here.

Also, how hard is this to install? I cannot weld it, should I take it somewhere to be welded and if so how much would that cost (I am in MD)?

Thanks in advance for the help.

2.25''

Center in/ center out would be best (I got center in/offset out and had to due some maneuvering)

Fairly easy to install....but I did it with a welder. It's possible to cut everything off with a cut-off wheel and use exhaust clamps but I would recommend taking it somewhere to get welded up. Shouldn't be more than $100 (they charge $50 here).

Also, great choice on the Thrush welded. I'm running it now and I love it. Not too loud, but noticeable.
 
Nice thanks for the info, I was actually reading your posts on it. Listened to it online and it sounds great! Cant wait to get it!

When I used clamps (with my OEM tailpipe) it worked its way free after a few months because the OEM tubing is way stiffer than aftermarket. I torqued the clamps down as far as I could without breaking the u-bolt (in fact I broke the first one), ended up welding it after that. The catalytic to muffler joint is clamped from the factory though, you should use a clamp on that unless you're doing a full stainless exhaust.
 
it is a really loud one basically a FM40 knock off for around $40. Also, little to no drone at highway speeds which is better than the FM40. People have great results with them and if you look it up on facebook you will see a good video or two.

I ordered mine today with a center inlet and an offset outlet, best option it seems. Should be in next week, not sure when I will install it though, but can't wait!
 
This is what I run with a dump just before the rear axle. Sounds nice at most speeds. Mine has a little drone but I think that is because of crappy installation via me.

You should like it if you want a little more growl to your exhaust.
 
Has anyone ran a 40 series flow master? I wonder what that would sound like...only reason I ask is I have a old one sitting in the garage.

i did for a little while. i got sick and tired of the highway droning and the straight exhaust tone just wasnt the same as a v8.

Yea that is what I was wanting too, didnt sound like that at all, sounds like a quite, broken Cummins.

Dont expect it to sound like your 67' Chevy...
 
Factory muffler is center inlet/offset outlet in 2.25". My setup is my sig.
