They do but the problem is, I don't think there is a 40 or 44 series that'll be a direct fit replacement for the 80 series you have. I'd look into a magnaflow or hooker muffler to replace.

Camaro, right? On my '97 Z28 I really didn't care about having 2 tailpipes out back so I installed a 3-in. Flowtech Warlock muffler, the one with the built-in cutout. http://www.summitracing.com/parts/BIG-50560FLT/ It has a nice rumble without cats and thru the muffler, no rasp. It's kinda quiet if you still have cats (speaking from an LT1 point-of-view). I attached a DMH electric cutout on the "bypass" portion, which gave me 12 rwhp on the dyno when I opened it. I kept the tailpipe short and had it tucked and turndowned nicely before the bumper for the V6 look.
If you have to have 2 tailpipes, my current '02 Trans Am has a Pypes Violator 3-in muffler. This is their Race-Pro version: http://pypesexhaust.com/gallery105.html The Violator version I have uses chambered tubing like Sweet Thunders; same set-up though......no S-curve or baffles or deflectors, just straight from the inlet to a Y, and out to 2 outlets.....this is probably the best flowing transverse muffler out there. If you look at the image of the shot straight-thru the muffler outlets, to the right is a glimpse of the Y-split following the inlet. It has a nice rumble on my stock manifold, catted LS1 and roars when you punch it. Slight rasp coming off the throttle.
I've always had to do a little more searching instead of following the bandwagon Hooker/Magnaflow everyone generally recommends.

I'd like to keep the dual exhaust though, so what I'd like to do is run the piping from the cutout area to the drivers side tip, and the piping from the "quiet" area to the passenger side tip. Is this a good idea?

I was looking into the Flowtech Warlocks as a possible way to simulate the Corvettes "Dual Mode" exhaust by using a heat riser valve.

I'll take you for a drive around the block this Friday at the meet so you can experience the quietness that is my sound deadened stock exhaust LS1 F-body.I was thinking instead, just attach said vacuum-modulated butterfly valve onto a manual cutout. It would leak a little bit, but electric cutouts start leaking eventually anyways, and this way is much cheaper and potentially more reliable. In the event it doesn't work I can just use the manual cutout like it was intended, or attach an electric cutout later.
