it is a great system and you will be happy you switched it. Mine works great, nice a quiet around the docks. I don't believe there are any issue with the system but obviously Nor-Tech is the best to consult you......Instead of buying the system, just buy my boat.......all done

Any db readings before/after?
What engines, HP, blower?
How much rpm reduction at wot
Any egt gauges, did it go up?
Thanks for info, curious on these details to get idea on how well they work.
