Sound outside the car is great. Sound inside the car above 4k rpm is also great. Inside and below 4k rpm, so much drone I still have a little headache from my 45 minute drive 3 hours later. Debating whether it's worth trying to fix or just find something else. Obviously the latter is the right answer, but that feels like losing...

Maybe try the JDM exhaust hangers. I’m surprised you are getting so much drone with the JDL FP.
