Thanks man. Its a broken link, but i think i found the page(s) you were refering to. Well, if its possible to be more confused than I was originally....then I am . Is it more than just engine horsepower that dictates what diameter pipe to use? I figure I am somewhere around 525hp at the crank and according to the exhaust calculators I should be running dual 3's or a single 3.75". I dont know how much the supercharger adds to the equation either. I REALLY want to get this right the first time and dont want to just "GO BIG" on the pipes and lose any precious power.

Whats the worst thing that could hapen if you opted on the smaller side? You lose a little top end and have a stronger bottom end, which is a good thing for a big heavy truck IMO, at least on the street.

Yeah yeah...I know.....to many questions.
Was just thinking today, about something. Wondering if i would be better off with an X-pipe like this....
then going true duals into 2 seperate mufflers? Or if I would be better with going into "one" X-pipe muffler where the X-pipe was actually inside the muffler? Also, should I be trying to get the CATs as close to the headers as possible and should the X-pipe be before the CATs or after?

everyone says the x is the way to go... if you want some real deal pieces (serious prices to go along with them), check out Burns Stainless, they'll have anything you need for exhaust piping.

I was always told to go a little bigger exhaust on FI engines. Point was the blower/turbo would make up for power that would be lost down low. Also for any given RPM an FI engine will be moving more air through it than an N/A would.

You might check with Dynatech Headers. They make all kinds of exhaust parts and I am sure their "X" pipe is much less expensive than the one you were looking at. I believe you are on the right track with your exhaust. Keep us posted as you move forward. Good luck!
