3in. pipe definitely should not be restrictive considering you are going for the full monty. However, I'm betting any gains from the larger pipe would be negated by the stock muffler.
There's a gazillion mufflers (loud/not-so-loud) on the market. Why stick with the stock muffler if you are going to all the trouble of upgrading the rest of the exhaust system?
Any possibility that you would lose low-end torque (not in great supply anyway) with the larger diameter pipe?
JMHO. I could be wrong.

restrictive??? you mean,'un'restrictive...right?
3 inch diameter from your y-pipe to your exhaust maybe a bit too excessive...might suffer from loss of low end power..besides..even with my 2.5 inch pipings..the car's loud as a #@$%!

I was asking if the muffler would restrict the 3 in. piping. I am doing this because it will help the 'secret sauce'

No in wont be restricted but without a supercharger, it really isn't necessary!!...
Also, you're going to have lots of problems with fitment...(not saying it wont fit!)
Bigger piping doesn't always mean faster car... It this secret sauce is what I think it is, go for it and keep us updated!!!..

Sheldon, straight up stick to 2.5" Mid Pipe, and continue the 2.5" from the rear section flange to the muffler. I had my factory Y-Pipe cut and gutted along w/ the front manifold.
I currently am running a dual "jet-fogger" system one jetted for 100shot, the other jetted for 50 shot. I have two separate bottles, separate solenoids all painted zinc black. All SS lines were painted in zinc black as well. The system feeds to a custom plate before the TB. This is all custom built, the only components I used was NX Wet Kit, and Carbon Fiber Bottles w/ NOS Bottle heaters.
I usually avoid running the juice, but when I do, its an experience you don't forget. I've had witnesses see a flame shoot after a 1st and 2nd gear run, this is from a factory muffler. I drive the car daily, and 2.5" is more than enough to get you by, but 3.0" unless you will constantly run nitrous, its not worth it.
BTW good luck fitting 3.0" piping past the rear beam crossmember. I couldn't squeeze my pinky in there w/ 3.0" system, I constantly banged unless I welded in a brace to support the muffler from banging the cross member. The problem after that...the flange at the cat that connects the Cat to the Mid Pipe cracked cause there was very little give, and w/ all the hard launches, the weak point was my MIG weld from the flange to mid pipe.
