I went with a 2.5" after cat back exhaust with a Spin Tech muffler. I love it. It starts out with a deeper sound than stock, but flattens off at 3500 RPM. With the Sportage typically running at well above 3500 RPM when driving the sound is just deeper than stock, but not loud. I had a 4" tip on it that made it louder becasue the shop didn't have the 3" tip I wanted when I had it installed. It recently rusted off, so now I'm going to have them redo the tail pipe with just a 3" tip instead. I'll probably have them cut out the cat when I do it and have it replaced with a High Flow cat.
