can u make an fbody sound like a vette?
I was gonna say run an x pipe and that gets you real close, but noticed you have an x, so?
Usually the biggest difference in vettes and f bodys is a y pipe single exit exhaust compared to an x pipe with duals, but hell you probably already know that.

First off, 98-99 LS1's had different cams in the motor between the F-body and Corvette. If you have an older F-body, it'll sound different based on this alone.
Second, it's impossible to get a true dual setup in the same way a Corvette has it. The Corvette is designed for true duals. You can run equal length pipes on a Corvette, which will contribute to its sound. In an F-body, you can't put a proper true dual setup on it. You will wind up with one side significantly longer than the other. In the Corvette, you can have mirror bends. You'll have the same bends on the driver's side as the right side. On the F-body, they'll be completely different everywhere. You'll NEVER get the exact Corvette sound because you can't fit anything close to a Corvette true dual setup on your car.
Third, the F-body has a completely different natural frequency than the Corvette. There's a reason why the F-body tends to rasp and hum inside the car right around ~2100-2300 rpm's. It's the resonance of the chassis. The Corvette's will do it at a different rpm. The F-body chassis will change the sound of the exhaust enough to make it noticeably different than the Corvette.
Forth, you won't be able to put the mufflers in the same place on the F-body as you will a Corvette. Muffler placement changes exhaust significantly. Don't believe me? Run single chambers in the center of the chassis, then run them right before the tips. I've heard sound clips of each setup. They're significantly different sounding.
That's just off the top of my head. There's a reason you've never heard an F-body sound like a Corvette
Honestly, the closest I've ever heard is a Corsa catback on a completely stock car. My car when it was lid/catback only sounded like a cross between a Corvette and a Mustang. Now that I have headers on, it doesn't sound anything CLOSE to what it used to sound like. It's a lot more tinny sounding, so I just leave the cutout open all the time

thanks choco... i understand i cant make the bends the same as the vette i have a comp cam to start with so it has nothing to do with the years for me .... i have hooker longtubes which you are right... they arent equal length on both sides....but i have continued the 3" from the collector all the way to the dumps...i know the headers are different (bends shape length) which do contribute but i have the same motor as the 98 ls1 vette so shouldnt the sound be somewhat similar with the same sized x piping and resonators. i dont have the same bends as the vette does behind the bumper and im going under axle vs. the vette over the irs... and i will be putting the stingers right before the tips like the vette...thank god that i dont have rasp!! the rasp i believe comes from the y pipe where the exhaust gasses merge against each other at the Y and the rasp comes from the pressure of the two pipes deflecting against where they meet each other not the chassis.... now exhaust does have a resonation off the chassis like you said but im describing behind the car sound....
The sound is inside the pipes. It doesnt matter what it sounds like inside.
Cam difference? With all the cam changes vettes and f bodiess go through?
I cant bolt a vette system on an f body, but I can pretty much build the same exact system that will fit an f body.
They made a joke about how the Firebird sounded better than the vette.
and this was before the cam!
