what exhaust!?

[lilskater519]

this spring i want to get a larger exhaust before i hit the dyno.
my set up is as follows:
Jdm H22A
Kidd racing 4-1 narrow tube drag header w/ 2.5" collector
egay 2.25" exhaust with no cat.
custom 3" sri
blox filter and velocity stack
s2 intake manifold
s2 70mm throttle body
hondata heat sheild gasket
hondata s300.

so heres the question:

what would be the best exhaust set up to see larger gains before dyno day?
allot of people speak highly of 2.75 or 3" on hswaps.
right now im looking at
-buddy club spec 2(i think is only 2.5")
-custom bent 2.75" exhaust with what ever muffler is the least restricting.
-try and find somone to replicate a spec 2 but in 2.75 or 3"

and i am very concerned about achieving better ground clearance also.
heres how low it sits now.

thanks for the help

In all honestly, If your not aiming for anything within the 300whp mark or higher. 2.5" piping is more then enough of course if you want more efficient go with mandrel bend piping instead of crush bends.

Its always been a rule of thumb when trying to get the most out of exhaust system its to match the piping size with the collector size.

Oh and if your worried about ground clearance. Look into getting Vbands =D

ill never see 300 whp n/a so in not concerned about that.
people with h swaps have seen 7-10 whp from going from 2.5-3" which is why i draw this question.
vbands?

It could possibly that the tune changed and thats what gained power but of course I could be wrong.

And yes Vbands
