I'm back again! If some of you remember, I had the Castro Motorsport race exhaust installed on my car, but the common complaint was how much it droned. Unfortunately, that's just the nature of the beast (catless downpipe + straight pipe with resonators = loud). However, due to circumstances, I had to get the race exhaust removed at Castro, so I took that opportunity to get their Sport Exhaust installed. This exhaust is definitely more quiet and does not drone, but it isn't as aggressive sounding as the race exhaust (as expected, since the sport exhaust has a muffler). It still sounds really good though IMO and looks great with the polished double walled tips. Enough words, pictures and video to follow.
