Looking at getting a new muffler, what size inlet do i need? and does it need to be centered or offset?

Look at your current exhaust to answer those questions. Unless your looking to change the entire system.

meh, its cold out, and night. i figured itd just be easier to ask, then to actually go outside and find out.

offset and 2 and 1/4 or 2 and 1/2 can work they will just have to flare you stock pipe to work on the 2 and 1/2

at the muffler it is 2 1/4", if your keeping the tailpipe you need an offset, if your just going to run a dump, you wont need the offset

Outlet of cat is 2.25"

Sorry to thread jack but I didnt want to start a whole new thread. Im wantin to put a flowmaster 40 series on and im wondering if it has to be welded or can I just do it myself and use the pipe clamps????

You can use clamps to get the job done, you may have some leaks though. Nothing a lil muffler putty wont fix. And the factory muffler is center inlet/offset outlet with 2 1/4" piping. You may find that you'll have to cut the old muffler off of the tailpipe though. that's what I had to do when I did my first attempt at an exhaust. It was kinda a pain in the butt but I got it done, I used a cheapo thrush turbo muffler and I got pretty nice tone from that setup.
