What power should i expect?
 

My car is a jdm sti my06, currently running 323.5 ps and 439NM with aTrust pe2 catback exhaust, an sti panel filter and a remap...
My next mods are going to be a SYMS downpipe(decat) and an AVC-R boost controller and a walbro 255 fuel pump and Tomei Expreme Headers along with a new remap...
What power should i expect from this and what torque?
thanks,
Charis

bttt

Keep the Subaru equal length headers, i dont know anyone who makes them as good as the standard item :) but a full decat and remap will see you about 360bhp and similar torque :)

Tony:)

the tomei headers are also equal length tony;)

its not the equal length bit Tony was referring to, he was suggesting that the oe item is top notch quality and unlikely to crack and cause you bother later down the line
