same exact muffler... i've had the Summits on 2 trucks, and Flowmasters on 4. i've got a thing for buying slightly used Flowmasters for dirt cheap, otherwise they'd all be Summit mufflers.

I got a generic Flowmaster 40 series from www.performance-curve.com. Works great, sounds good. Here is a vid...

does anyone know if my truck, 96 gmc yukon 4x4 5.7 has 2 inch inlets, thats the number i came up with by doing the math from the circumfrance, thanks for the help

You have factory 2" inlets. I'd purchase 2.25" inlet/outlets though.
