Exhaust piping recommendations please!

Ok I need some help deciding what to do with my exhaust.
basically right now i have a modified ITR bpipe, and a custom axleback.

the axle back is 2.5" but hits on my swaybar so I need to get it rebuilt.
and the ITR bpipe is 2.25" but where it connects to the axleback, it dips down to like 2" so i need to get that fixed as well.

What I'm not sure of what to do, is whether or not to rebuild the axle back in 2.5" or 2.25" ??

I'm running a d15b JRSC 9.5psi,
it makes around 175-180whp and 135tq

So i'm wondering, which would be better?
the 2.25 end to end piping
or 2.25 to 2.5" setup ??

lmk what you think,
thanks.

cant afford a completely new exhaust.
the bpipe is gonna be 2.25.

i just need to know if it's better for specific setup to have the piping all one diameter(even though its a smaller 2.25) or widen to 2.5" at the axle.

the muffler is a 2.5" straight thru btw.

thanks

Well I know where you're coming from. 2.5" axle back will be better than 2.25" axle back.
