The restrictive 1" ID oem tail pipe assembly unbolts in the North American 2021 T7.  Replaced it with a 1.5" ID pipe w/screen attached as a spark arrestor. It improved the through put & sound...a little louder, deeper & more roarty...most noticeable at idle & blipping the throttle...best listened to on headphones or PC speakers w/subwoofer to get the full impact...too bad the oem muffler is so ugly & heavy...would be even better decatted :)  Bonus sound track below with no muffler...just oem cat..sounds mean! OEM Tail Pipe/Spark arrestor Assembly 1.5" tail pipe mod no muffler

 This was a 2 stage mod where the restrictive oem spark arrestor assembly was removed from the oem 1.5" tail pipe May 2015.  I later made a custom 1.75" tail pipe for increased flow & sound May 2016.
