lol ya I know you can sound good and have nothing to show from it, my first camaro was like that lol. Had a little 305 in it, just did some minor work to the motor but it ran good with no leaks so I didn't feel like replacing it yet but everyone thought it had something better in it. Ya I am betting Flowmaster 40 series for sure with dumps under the car. And if it IS a 307, the Z28 badges could be put on for fun. He says it's an X11 code in the beginning, so that could be either a plain Camaro (307) or the 350SS.
