Which True Dual Setup???
Which True Dual Setup??? So which of these should I go with? I've done a search and have seen many pics but I'm torn between the two still.... so. It's seems that it's gonna be either one or the other since there's probably not enough room to do both. this setup will be custom made also. will having cats be that much quieter? what are your guy's opinions? thanks!
Are you still kicking around the come off headers, then to cats, then to mufflers, then dumped idea with no x-pipe?
Dual cutouts on a TD system that does not have cats would be pointless IMO.

I honestly can't see the point in having cutouts with the only "mufflers" being the resonators. If you're wanting to do the cutouts, why not get quiet mufflers after them instead? I doubt it will sound any different going out the cutouts than it would going through resonators
As for the cats/resonator combo, I can't really say, since I've never heard that setup before. I would imagine it would still be pretty loud since your only real restriction will be the cats. It won't be quite as loud as say, open headers, but it probably won't be awfully far behind either. I used to be that loud with sweet thunder duals, and it does get old after a while. Did to me at least
Given your setup and what you're wanting, I would probably do dual cutouts after the headers somewhere, and slap on a quiet crossflow muffler, that way you can be quiet when cruising the interstate, and then open up and have the rasp-free true dual sound of the cutouts. A guy locally runs that setup, you would swear it was running true duals by how it sounds at WOT, but it's a dual cutout setup after the headers. This however is just my opinion
Unless of course you're looking for the weight savings of the duals, then scratch what I suggested

If you're now considering having larger, quieter mufflers back there (after an X, I guessing?), which ones are you going to go with?
As everyone else said, it makes absolutely zero sense to have cutouts on a dual system that is running catless with resonators because there will be zero HP to be gained and not a ton of sound difference. I'd suggest having the duals fairly quiet with some larger mufflers and running cutouts if you want a difference in sound sometimes (seeing as you won't lose any HP through the mufflers).

cats with a TD setup should still be very loud. think about it: putting a loudmouth on a stock car is still loud. that was a y-pipe setup, stock manifolds and choking stock cats. if you put on LT's, an x-pipe and high flow cats, it's going to be twice as loud as a loudmouth. it'll still be loud as hell. get the cats. it's only going to clean up the sound. as scotty said, cutouts = pointless on that setup.

If you were to run dual cut-outs after the headers, but run a coupe of resonators after the X, the only "gain" you would see would be a louder idle. I installed my long-tube Pacesetters myself and ran open headers for a day or so waiting for the muffler shop to get ready for me to come in and weld up the rest of my system (Summit's universal X-pipe and two Dynomax Bullet Race Mufflers dumped before the axle). The only difference I found (between open headers and a X-pipe/resonator setup), was in sound. It was louder at idle and the sound came out under my feet (open headers) instead of the sound coming out under the rear seats now (X-pipe/resonator setup). But again, the only sound difference was at idle. The only time I found that the resonators were quieter was at idle. I mean it might be a little quieter when I give it some gas with the resonators on there, but not much quieter than open headers.

doing some grave diggin huh boys?
basically I've decided to go to a setup basically like yours... gonna have to run open headers for maybe a few days to a week and then having a custom true dual x pipe w/hi flow cats and two dynomax bullet mufflers dumped
south bay as in los altos/mt. view area (highly doubt you've seen me as I've only seen about 3 f-bod's in 2 yrs. while driving my car
