Thundercone Slip-On Mufflers by Thunderheader
- Fits Harley Davidson motorcycles with removable slip-on mufflers
- Designed with the utmost precision, these mufflers are engineered to deliver maximum horsepower without sacrificing low-end torque
- Improved performance and enhanced throttle response allow you to unleash the full power of your machine
- Experience unrivaled performance and throttle response with our anti-reversion design for optimal performance
- Features a thoughtfully designed structure that maximizes exhaust scavenging. As the reverse flow enters the collector, the diffuser deflects it through vents. The pyramidal trap and apertures work their magic by impeding the reverse flow, providing ample time for the exhaust valve to close
- The constant velocity of exhaust gases over the entire length of the system ensures superior exhaust scavenging capabilities for optimal power delivery
- For added protection and peace of mind, we recommend ordering our heat shields along with your mufflers
- Heat shields are optional
Thunderheader exhaust systems are legal for closed-course competition use only
