Thunderheader Thundercone Slip-On Mufflers for 1995-Up Harley-Davidson Touring Softail Dyna
There’s a certain satisfaction in a bike that responds the instant you ask — snap the throttle and feel the engine pull hard through the RPMs without hesitation or flutter. Thundercone slip-ons from Thunderheader’s racing program deliver exactly that: a surge of exhaust efficiency that translates directly into stronger throttle feel, better mid-range pull, and an exhaust note that suits a machine built to move.
Key Features
- Anti-reversion exhaust design eliminates backflow for immediate, consistent throttle response across the RPM range
- Pyramidal trap and diffuser vent system channels and impedes reverse exhaust flow before it can reach the exhaust valve
- Constant exhaust gas velocity across the full muffler length maximizes scavenging efficiency for optimal power delivery
- Available in Chrome and Black finishes to match factory or custom styling
- Touring and Softail variations sold as a pair; Dyna variation sold as a single — all include installation hardware
- Optional heat shields available separately — recommended for rider protection and a finished appearance
- Closed-course competition use only
