My car is a heads/cam SS, with headers, Borla atak with NPP. It's LOUD!!!
To get my exhaust low enough for the track I put the Borla resonators in. It didn't really lower the volume at all, just got rid of the rasp. I ended up getting a stock NON NPP muffler and that really made a difference. Talking 25+ decibals worth. I have some 3 inch moroso spiral flows to weld in if I need to get it even quieter. Thunderhill is 103db, so that was my goal to start.
My plan is to just put the stock muffler in for track days only, it's a pretty easy swap.
