6 reviews for S&S CYCLE 4-1/2″ Grand National Slip-On Muffler

  1. Marty

    Yo this S&S slip-on totally transforms my Sporty, gives it that old school rumble I’ve been looking for while letting the engine breathe better, install was easy and it looks sick.

  2. Bryce

    The Grand National slip on muffler gives my Sportster a nice deep rumble without being too loud, it looks great and seems well-made too.

  3. Larry

    This mediocre muffler fits my Sportster and lets the engine breathe a bit more, though the removable baffle means I can really annoy people when I feel like it.

  4. Paul

    The 4-1/2 inch Grand National Slip-On Muffler for Harley-Davidson Sportsters delivers on the classic styling and performance promises expected from this reasonably priced and easy to install muffler that gives my bike a nice vintage vibe and deeper exhaust note.

  5. Andy

    This muffler is sweet, it sounds so much better than the stock one I had and really lets my engine breathe better, installation was mad easy too.

  6. Jerry

    I’ve been riding my Nightster with the new S&S Grand National slip-on muffler for a few weeks and I’m very happy with it. This muffler really compliments the classic Sportster styling of the Nightster while letting the modern engine breathe better and adding a much needed throaty exhaust note.
