04 Chevy Silverado 5.3L Flowmaster 40 series

My 2004 chevy silverado Z71 5.3L with the flowmaster original 40 series two chamber muffler. si/so Exhaust. All i did is i swapped out the old muffler and put this one in to replace it with additional piping of course. Which means the piping i believe is 2 3/4. Enjoy!
