Hey Folks- After many months of waiting, I got my Dubach pipe. I cannot rave enough about this pipe. The construction is top notch and the performance gains have been very noticeable! Down low it pulls amazingly and doesn't appear to have taken anything away from the top end. Throttle response is instantaneous and feels like it will rev for ever. Another great attribute...almost a 1lb weight savings(claimed). This is 10x better experience than I have had with other brands I have experimented with!
