I think the Blue stripes look great on black car. I remember seeing a picture of one somewhere... Anyway when I first heard of that combo I thought the blue would stick out to much, but after seeing it I liked it, but I think it will get extremes in opinions, either it will be loved or hated.
I have the Roush A/B on mine and love them. I had a chance yesterday to follow my car for a few miles and hearing it from behind was crazy! It sounded like a race car but idles like a regular exhaust. I have always felt it had a raspy sound and hearing it from behind solidified that opinion. It is very raspy! My wife only had it to about 4500rpm and about 3/4 throttle so I can only imagine what it sounds like screaming through the gears!
