Before you guys slam me for not searching.....I have, but am just short on time to read all the exhaust posts.

I have a 02 Tahoe with a 5.3 and want to replace the muffler with something a little louder in the near future. What is the diameter of my stock system....2.5" or 3.0" ?? Also, I believe the stock muffler is 7x9x28, is that correct? I am on a very strict budget so I am probably going to go with a Dynomax Super Turbo. I was looking at part#: 17748 which is 4 1/4"x 9 3/4" x 25 1/4" with 2 1/2" in/out....that should work right?? I don't want anything really loud, just a little louder than stock. Any help would be greatly appreciated.

2.75" = stock

I would get a 3" :imo

Up to you though.
Yeah I'd do the 3", but on basically stock you won't see much difference between the 2.5" and the 3"

I had a Super Turbo on my '99 Z71 truck, sounded good.
