Hogan Catless Downpipe with No Mufflers!

Just picked up the Hogan catless downpipe and am wondering how ridiculously loud my Impala is going to sound with that downpipe, no mufflers (I had them replaced with straight pipes) and just the stock resonator.

Has anyone run this combo before?

I assume I'll need to buy mufflers, but I'm just wondering what to expect!

It's gonna sound unrefined and RASPY but the resonator might help with some of that rasp. Even so it will be super loud and you will be buying mufflers immediately, I'm thinking.

Check out my vids I've posted...LOUD as **** and hell of raspy. I've left the cutout open for the last 1-2 months in a row as I've gotten used to the sickness of it.
