Finished installing the MAD single midpipe today. I'm happy with it. It's has slightly more bass than the AA midpipe. And has less rasp than a Xpipe by itself. The turbo spool is way more pronounced now.
Fitment was spot on. No rattles or leaks. I'll stick with it for the long haul.
Made a super quick video:
Use headphones to get representative audio of how it sounds in person.
