NPP Exhaust Question

Got kicked off the track for being to loud. 108DP, Limit is 104DP. Car has 2" kooks with no cats into the factory suitcase. Does any one know if there is a way to do a mod so the valves stay slightly closed under full throttle. I tried putting the exhaust in tour but full throttle over ridded that thought. Any ideas would be great! I would like to do late night drags at the local track but not changing my setup
