    My 97 center muffler is needing replacement. I have no interest in more noise or performance but feel that the middle muffler is a bit superfluous.

    Which option is recommended for a replacement of the muffler ? X / H OR straight to keep the most optimal balance between good noise (no droning) and performance?

    Thanks and merry Christmas

    If you do not care that much about hp, then an X-pipe or one of Fabio's H pipes will eliminate the drone and still increase hp. Max hp would be to do what the factory did and replace with straight pipes. All 575Ms from late Summer 2003 came from the factory with straight pipes.

    Fabio's H pipe will give more hp than an X-pipe, with a nice sound, too.

    I have X pipe with X-OST mufflers on 550. No drone. Good sound. Can talk in car at any speed. Mufflers are valve delete.I even put stock mufflers on for concourse judging. No added noise.

    I went with a custom made H pipe in the end and its sounds different at idle but and above 90mph. Its no louder, just deeper and I like it! Additionally, it has no drone..

    Is your car a 550 or 575? What rear mufflers are you running?
