As promised, here is the final version installed on my car.
Before you ask, no the burn marks on my bumper are not from this muffler lol
and the scratch on the bottom is because My car is VERY low, and I tagged the ground with my tips.
and yes I left them huge on purpose, so enjoy
Dyno for full system:
Here's a Couple videos, the first is a rev-up . The car has full headers (catless) stock midpipes including resonator - custom MMW "City Sleeper" Muffler
