I need an exhaust answer quick so I can order parts!

My cousin and I are doing some custom dual exhaust for my uncle/his dad, this weekend. I don't have the truck in front of me, or I'd look. But, what I need to know is on a 2001 Silverado 1500 with a 4.8, what size is the exhaust pipe going into the stock muffler?? They want me to order the muffler today, and I'm not sure if its a 2.5" inlet or 3" inlet??

On our 01' Tahoe I used a 3" Inlet/Dual Outlet. Not sure if the same one will work on his truck.

Thanks.

I think 4.8 is 2.5 and the 5.3 has 2.75". Either way I would prolly order the 3" and make it work :)

Yeah, well if we can order the correct one and just slip it on, obviously that'll make my life easier. But, if we have to order a 3" inlet, I can make reducers to whatever size we need.
