Because of the new noise limits, I will be swapping my T-4 back to the stockie exhaust. This needs to be done so I can legally race in an upcoming Hare Scramble. I have a K&N with Dyno-jet was wondering if I will need to re-jet if going back to the stockie?? Thanx in advance...[img]i/expressions/face-icon-small-wink.gif[/img][img]i/expressions/face-icon-small-cool.gif[/img]
