Went with the Fabspeed Maxflo. Should have gone with the supercup or Borla. The Maxflo even with 4,000 miles is just too quiet. A little burble but almost mute. Zero pops and cracked. Figment wasn't easy and I've re-installed once. It says out of the bumper. Check engine light goes on intermittently but that may be totally unrelated and just a bad O2 sensor. Scan notes heat drop across cat, etc... Finish, welds, etc look very nice. Overall I made the wrong call.
