I recently fitted the ZARD Slip-On (No ABS) “Penta” Exhaust to my 2008 Triumph Rocket III, and the difference is night and day. The craftsmanship is superb—sturdy, lightweight, and finished to a high standard that really complements the massive presence of the Rocket. Installation was straightforward, and everything lined up perfectly.

The sound is where this system really shines. It gives the bike a deep, thunderous growl that finally matches the Rocket’s raw power. At the same time, it’s well-balanced—not obnoxious when cruising, but absolutely commanding when you roll on the throttle. Performance feels sharper too, with smoother throttle response and stronger pull in the mid-range.

This exhaust has completely elevated my Rocket III—it feels and sounds like the machine it was always meant to be.

The sound is nothing short of epic. The Rocket finally has the deep, rumbling growl it deserves, giving it a commanding presence on the road without being overbearing at cruising speeds.
