Sound comparison between a Borla X-pipe and Atak cat-back in unmuffled mode and a mid-mounted Flowmaster two-chamber Super 44 muffler (Part number 8425454) in place of the X-pipe on. a Vortech supercharged 2018 Mustang GT. Similar sound to an original 40 series muffler, but better flowing. Since this is a single-muffler installation, I wanted the best-flowing two-chamber Flowmaster version, so I chose the Super 44.
Why did I mid-mount it rather than use two Flowmaster mufflers in the rear location like in Flowmaster's American Thunder cat-back system? I wanted more of a classic Flowmaster tone, and I reason that having a length of tailpipe after the muffler (like in a truck or a Fox body Mustang) would give me more of the iconic Flowmaster tone. Did it succeed? Let me know what you think in the comments.
