hp gain from headers and exhaust

[jspec civic]

guys,

what am i expected to gain from my b16b after putting a x force 4-2-1 and itr system with high flow cat and adjusting my cam gears..before those mods it was pulling 97.8kW atw tuned with jdm itr ecu and piggy back blue emanage and top fuel air intake, stock exhaust...

thanks

what is itr system?

[jspec civic]

itr catback..

should be pretty stable I'd imagine, that's a realitively nice number.


Plus dynos are a guide, creating the same situation twice or three times is near impossible, too many variables.

expect to gain around 10kw and not much more.

Supposedly 4-2-1 is better for midrange, whereas a 4-1 will give you top end. So expect midrange gains instead of a higher max kw value.

treat your b16b to something better than xforce. jdm 4-1 perhaps

now that i've got the x force headers and itr catback on, i think my vtec is kicking in too late 6K to 6.2K is this normal..im sure when i had the stock it was 5.8k..
