RSS center delete dB level
Does anyone know the max dBs a 7.2 with an RSS center delete and otherwise stock exhaust will produce?
Have a 103dB track day coming up and hoping not to find out the hard way…

You should be ok with a slight lift after Turn 5 (assuming this is Laguna 
) with a center bypass but it's very close. It also depends on conditions that day - heavy fog in the morning will amplify sound. The newer 4.0L DFI GT cars blow sound without the center muffler. That I know for a fact because a friend of ours got meatballed.

As of a few months ago, NCRC also said there’s a mobile meter checking sound from the left side too - but I’ve no idea if that’s in place.
