After many inquires on an exhaust system upgrade
for the Holden Barina SRI we decided to see what improvement if any could be achieved by changing
the factory exhaust system to custom headers and
a 2 1/4" free flowing system. With all three dyno runs the air intake temperature was over 30deg , even on a hot day the torque and power increase achieved is pretty good. With some tuning i am quite sure there is more power to be gained

DYNO RESULTS
Full standard system 72.6kw @wheels
Headers /cat/ orig system 75.1kw @wheels
Headers /cat/ sports system 79.0kw @wheels
