    What diameter tubing is the y-pipe at the catalytic converter? And, is that ID or OD? My best guess is it's 2.5" OD. I want to get a 3" cat and a 3" muffler, but not sure of the tubing size. Thanks

    I run a single line from the crossover back a 3" catco converter, 3" flo-pro muffler, and 3" exhaust pipe to the rear, has a real mellow sound, untill you wrap it open then it (I think) sounds great, it dosen't crack, or pop when you get off it....Mikey likes it
