    Great Sound And Performance!
    Fit and finish was great, but the pipe is made for all body styles, so it was about 2" short for my screw. Downstream end flange is fixed, so I had to rotate the resonator to get it lined up. Neither were big issues, just took a bit longer (~2.5hrs total) than I was expecting.
