An electric cutout would be the cheapest and easiest route.

It essentially allows you to run an open exhaust at will. With an electric cutout, a solenoid opens and closes and is usually installed right after the y-pipe.

Jeff wrote up a good thread about it - http://www.ls1.com/forums/showthread.php?t=137873

so it is installed right before my loudmouth "resonator"

and how much louder would it be? because the loudmouth "resonator" is basically like straight pipe

Most install one right after the y-pipe. And it would be pretty close to running open headers. If you check on youtube, you can find quite a few soundclips.

Most people leave their exhaust as is, that way they can have it quieter when they want, and louder when they want. Check out KYSpeed - http://kyspeed.com/index.php?main_pa...d020001eb5e371

I like "Knight's" cutout idea

LTs and a bumpstick

I've got a quiet idle with LT headers and a Loudmouth, both when I had an ORY and even my catted ORY now. Seems like Cams are the solution to a loud idle, along with a bunch of confusion if you don't know engine internals.

This.

A cam will open up your exhaust duration and increase flow. This will give you the louder tone you seek. I assume you want the V8 rumble?
