I was holding my breath , and now am blue in the face, waiting for the INFAMOUS SUPER QUIET (ok, by 5 decibles) FMF POWER CORE FOUR SQUARED that has ground thrashing, golf course destroying, booming bottom end. Now that I find out it's almost as noisy as everything else, I dumped that idea. I am looking for a tunable pipe that offers great bottom end (loss of top end is fine) and is NO louder than the stock exhaust w/ insert removed. Any ideas? Much obliged! Kevin, I think I went over the line with that one, in New Hampshire.
