The original vid with the black GT is my friends car. It sounds good but would sound better with something other than the flows. Its still raspy. He now has Pypes LT, o/r H, flows, still a little raspy for me. I run Stingers and love the sound and tone of them. the cams are very nice. Low end power and street manners are good. Pulls good all the way up, after 4k they scream. Nice cams if I was NA I would definitely consider these.
