I thoroughly researched all the Flow Master systems on line. I ordered with a bit of trepidation the American Thunder thinking it might be too loud for my 5.3l Triton according to other reviews. I don't mean to be snarky with this comment but if you don't want some deep throated rumble...leave your stock pipes on! I love these pipes and almost wish I had gone with the Outlaw series, but American Thunder will make you smile. Yes, a little drone under hiway speeds but not enough to annoy.
