@driftbuddy this engine does not need back pressure so it gains hp with opened up exhaust, most engines are like this nowadays, unless it has o2 sensors behind the cat then you must keep the catalytic converters on without computer modification, but louder open exhaust mostly gains hp
why are you zoomed in on only one pipe? i see it has duals...I would be focusing on showing off the duals instead of one pipe...
