Should I go to 4"?

[96LT1355Z28]

Here are pics of my current exhaust setup. It's Pacesetter LT's with their 3" Y and a 1 chamber 3" in/out muffler. I'm wanting to know if anyone thinks it would be bennifical for me to go with the same steup but a 4" pipe and muffler where the Y comes together? Or is 3" enough?

Thanks,

You might pick up a little, but I dont see an NA setup picking up a whole lot from 4"

I have a 4' mufflex. Good stuff.

Your y-pipe is probably bottlenecking you more than the intermediate pipe. I wouldn't mess with it unless your going to dual 3".

I do not see it worth the money to change it up.

Thanks guys! That's one less thing on my long list of to do's!
