sounds like a plan...though i dont think it will be quite with LT's, a 3" y and basically a 4" exhaust system up until the muffler but who knows maybe your on to something???

I going to retein my factory SLP muffler and tail pipes.I spect it louder than but queiter than a Mufflex sist.In 2 week i going to have data on how the sist. works.Tomorrow i going to go to the track to set a base times slips for my car.Them i going to go again with the LT & Y pipe.
Why not just have a y-pipe made with dual 3" cutouts, then just use the 3" catback? I have a 4" system with a Spintech muffler, and then dual cutouts on the y-pipe. It sounds mean as hell with them open. I did it purely for the sound though, didn't gain much of anything by opening it up.

Verdad Gallardo I have a custom setup that's based off of some Mufflex pipes I got from a local guy. It uses the 4" Spintech muffler with dual outlets. I love the sound, but I'm switching to true duals with fullsized mufflers for other reasons. It isn't as loud as you'd think, but remember that 4" systems aren't going to be exactly quiet. If it's worth anything, I'm gonna probably be using Spintech mufflers for the duals too.

I want to use just one cut first is less expensive one cutout & second space saving under the car.I don't really care about how it sound with open cutout.But want it as quiet as possible in the street.

I sure like it. I've tried a few exhaust configurations and this one is BY FAR my favorite one. I don't think I'll ever change it. The only problem is, when cruising, my exhaust is SOOOOOOO quiet that I can hear my valvetrain puuurrrrrring.
