That's interesting, I didn't consider the type of tires for some reason. What tires would be considered quite but still high performance?

Most people overlook the tires .... arguably the biggest contributor to noise in this car.

PS2s and ContiSport IIs are quiet. GS-D3 also start out quiet (as do most tires). T1S's and 555s never seemed to be quiet for me though.

I will admit that when my car went back to stock ... I was amazed how much quieter and more liveable it was. I took off JWT, Kinetix, and Borla TD and I put a bunch of the panels back in the trunk area. The tires were stilll loud, but I'd bet there was a 6-9dB reduction in overall noise level.
