im pulling out the old muffler since its falling apart and putting in a flowmaster delta 40 series. What size inlet do i need. I am also going dual exhaust, so i know it should be 2.5 outlets since the pipe is 2.25 correcT?

My pipe is 2.5, on both sides... Usually you go smaller depending on engine, and if your going duals... If you have a v8 bigger pipes won't hurt but no gains after the muffler really it's such a smaller amount..

Do your research, is all I can tell you. I have been thru 3 different exhaust setups because I wasn't happy with the results. IMHO, if you are going duels, you will lose low end no matter what size you go with....or at least that was the case in my situation.

I also have a '97 5.2L truck. Here is what mine sounds like with a Flowmaster 40-series dual muffler:
http://www.dodgeforum.com/m_1272710/tm.htm
The muffler has a single inlet (2.5" probably) and dual outlets (either 2.25" or 2.5", not sure). I would probably go with 2.25" out if I were doing it. It sounds real mellow, and actually quiets down as the revs increase (I like that). There's no drone at all, and I was surprised by that. I don't know about any power gains/losses (because it was on the truck when I bought it), but it'll spin the 32" tires with moderate ease on dry pavement, so it couldn't have lost a lot of power. It's got a lot of low-end jump.

I don't know. It was on there when I bought it. The P.O.'s service records says it's a 40-series, but doesn't specify what type, or give a part number. And if Flowmaster molds any part numbers into the muffler case, they're on the top side, because nothing is visible from underneath.
But as quiet as it is (for a 40-series), I've gotta believe it's the Delta Flow model.
Edit: I will measure the case dimensions and inlet/outlet dimensions and see if I can determine what it is from the website.

Okay, my muffler is 13" long, and 4" tall, and 9" wide. Inlet is 3" (although the actual pipe size is 2.5"), and the outlets are 2.5" (although the actual pipe size is 2.25" (or maybe 2"). There is a part number with those dimensions for the original 40-series (430402). There's also a part number for the Delta Flow (9430402). And I can actually see the spot welds for the interior baffles on the outside (small deformations in the otherwise smooth surface) and there's only one "triangular" baffle in the middle of the muffler, and one "concave" curved baffle near the back. If you look at the photo on Flowmaster's website for the original 40-series (http://www.flowmastermufflers.com/40_orig.html), that's my muffler. Whatever it is, the muffler, the pipe size, something. You can hear it...and it's not loud. I was never a fan of Flowmaster mufflers, but I think this one sounds real nice.
