So I pulled the trigger and got the Resonated Cat-Back as well as the overpipe. Working now in combination with a motiv concepts catted front pipe.
The sound is just...wow

. Think I waked up the neighborhood with a cold start at 2 AM in the morning. lol.
I definitely feel a bump in midrange torque and the noise is just butter to my ears. I can even hear a little bit of boxer rumble coming out of this lovely tubes.
Next mod: Catted UEL header.
