Think the only benifit is more area to flow which lowers EGT's.

How do you like your exhaust? I'm getting one in the very near future but I haven't decided on the 4 or 5 inch. I'm gettin 4 inch downpipe, it's gonna be straight piped, with a big tip.

you are right, there will be very little difference from a 3.5" to a 4" maybe 50* if that and you wont even see that on the pyro gauge.
