Your B16A dyno results?

[dsp26]

Just wondering why did you opt for the 2.5" catback over the 2.25"? i would of thought that you would be loosing back pressure ultimately reducing peak power output

back pressure gives torque, trying to salvage torque out of a b16 is pointless imo... therefore allow the higher cam to breathe better in the rpm by just free-ing the flow instead.

if u want to gain some drivability in low rev get a light flywheel

i too have 2.5mandrel, but for me its coz i know i'll have sk2s2 cams later + higher CR.
