Quick update, i love the sound, but all the drone is most definitely at the 2500-3300RPM range.
(2300 and below for the most part quiet, 2400 sounds nice, and BAM 2500RPM things begin to shake, once you get past 3300 or 3500RPM all is good again). In city i can honestly say it drones , due to the constant acceleration and deceleration. And when i say drone, i mean it is quiet a loud and noticeable vibration drone. On the highway it is very quiet.
Would i do it again.....probably not. I love the sound, but definitely not for everyone. Luckily it wasn't expensive to make, and i can easily pop in the old exhaust with an exhaust sleeve adapter. May go AWE Exhaust in the future.

Maybe if you had Catless downpipe?
