I have the exact same exhaust configuration except I my secondary pipes don''t have the resonators. Was at Bondurant yesterday and it sounds amazing! It might be an issue for tracks that have a low sound limit (90-92 dB). You really hear it when you go by concrete barriers or a tunnel  So if you want to keep the stock headers, just put in the secondary test pipes and a good quality muffler. The Borla muffler came with the car when I bought it and I kept in because it didn't drone and sounded/looked great.
I did notice the oil temperature creeping up to ~240F. This is the highest I've seen in this car. Two factors may have affected this: new NHP headers (more air flow/fuel/heat) and high ambient air temp (95F). I'm leaning towards the hot air temp.
