2000 chevy tahoe muffler

[MattaKlecha123]

Does anybody know the stock exhaust pipe diameter? i believe its 3 inch center in (to the muffler) and 3 inch dual out. but i cannot find any mufflers (i want something louder like a flowmaster 44, or 40, or 10.) that fit.

I`m pretty sure it`s 2-3/4 inch in and out. If you`re set on any of the flowmasters you listed get ready for some really bad drone.
