My Mustang buddy only ran "Cherry Bomb Header mufflers" that 3-bolt flanged right off the collector, not much different than what you got but about 5 feet less of actual pipe: JHC, those were loud. You could hear him coming a block away.
Also there you can see the picture of where I welded that bong in for the O2 sensor!? LOL voice command! I'm going to leave the bong but I meant bung LOL
