exhaust pipe size?

What would be better pipe size to put on a 2004 f-350 v-10 3" or 3.5"???
Also where can I find a GOOD Y pipe?? Or would it be better to leave the stock Y in?? I'm going to doing my Exhaust very soon, just don't know the size of pipe to run, and don't know if the Y pipe is worth it.If anybody has these options on their truck let me know if ya like them or what you would prefer.. Thanks

The stock 3" size is fine. The y-pipe from SPD is worth it powerwise but you may not like the flutter and odd sounds it can unleash.

The 3" is fine. I changed out the Y-pipe on my last truck and what a waste other than it looked good.

I have an 01 250 and installed gibson headers that dump into individual 2.5" pipes then where the stock cat was i installed two shorty 3" converters and proceded to install 2 3" in and out magnaflow triple chamber mufflers. The tail pipes are 3" that end into 4 inch tips out under the bumper. There is no sound quite like a V10 unleashed!!!!!

Talking

The SPD Y-pipe with 3" exhaust pipe (stainless preferable) and
a Flowmaster 70 muffler is in our trucks. This is the perfect
setup that gives you a small boost in power that you can feel.
It also is louder, but not 'loud' with the FM70 series muffler.
You should notice a little bit better fuel mileage too.

Please consider an SCT custom tune, complete intake system,
Thorley long tube Tri-Y headers (or any long tube set-up will do,
for low-mid range power), synthetic oils in the engine & tranny &
air up your tires 5# over filled.
