While I was admiring the underside of my bran new 19 Silverado I noticed the exhaust pipe, immediately after the cat, is squished, like super flat... Has anyone replaced that section with a normal round piece of tubing? Did it make any improvements in sound/mpg? Seems like it must!

Selling my Texas Speed catless y-pipe. Was too loud for my daily driver with as much driving as I do daily, so I switched to a catted version. This is the y-pipe for the 5.3 motors, so it is 3" diameter pipes. Im located in Owasso, Oklahoma. Asking $150 shipped to lower 48.
