Worst Drone I Have Ever Heard

Today I was finishing up on a custom 934WG/Center Dump Muffler combo for a client and spied one of my still-born projects on the shelf. All the tools were out, the chop saw was set up and the custom exhaust had to come back off my car, so I thought what the hell toss this thing on and give it a go.
The "thing" was a 4.5"ID 50 state legal OBD II aftermarket CAT.
I've wanted to put something together for those who need or would like the option to use a catalytic converter. My muffler systems are modular so this dude just plugs in where the muffler body would normally go.
Well I got it all cobbled together and fired it up. First impression was that is is very loud. A touch louder than my Hooligan muffler. Not good. Then I took it for a ride. Holymotherofgod this thing is obnoxious! I have never in my life heard such an ear piercing drone! It actually hurt my ears from 1500prm-3000rpm.
The stock muffler on the 930's with cats is heavily chambered and brother now I know why. Taming this beast is going to be a challenge.
