Stock power at flywheel 160kw (my 99 and 2000?)
with 3" exhaust 189.1 kw 18% increase, quite reasonable for a 3"
with 3" and unichip 212.6kw, another 12%, about what y'd expect. This would be about 150kw atw.
Just a unichip alone would give a 10% increase. This would apply for the NA motors such as GX and RX for those questions on another thread. not a bad increase but not particularly good in terms of 'bang for bucks'.
