2.5 flows completley fine for anything upto and over 300bhp, there is just a few starlets on here who would benefit with anything bigger.

why do you want to replace with 2 inch? That will be way too small for 300HP... Back pressure will be through the roof and you wont make the power. I say 300HP as the T28 is large enough to flow that.

if i had a 3" downpipe i would'nt bother changing it, but if you did 2.5" will see 300+ easily enough without problems

If you have a 3" down pipe, why the change?

2" will be to restrictive, 2.5" will flow more than enough.
3" is ott unless you are packing serious power.
