Has anyone tried SpinTec mufflers? I've heard a couple of cars with them and depending on what model one has dictates how loud you are. One car was loud as hell(S/B Ford) but one with a 500+ hp LS Chevy was not loud at all. They both sounded good but I've never seen these mufflers before or read about any on here. Just asking because the guy who had the LS said these flow more and are quieter than the FlowMaster or Hooker mufflers he had used in the past. They look like they have no packing to burn out so they should sound the same year after year.
