Cobra 4" 909 Twins Slip-On Mufflers for Harley Davidson
The Cobra 909 Twins 4" slip-on mufflers are an ideal choice for Harley-Davidson enthusiasts seeking to enhance their bike's sound and aesthetics. These mufflers feature a sophisticated satin black or chrome finish, providing a sleek and modern appearance. Each muffler is crafted with a rolled inner tip, matched to an inner core that boasts a scalloped cut, delivering a unique and refined look.
Notably, these slip-ons come equipped with a constant velocity tuned core, specifically designed for the M8 engine, but they also perform exceptionally well with the Evolution or Twin Cam engine. This specialized design ensures an excellent sound quality, balancing depth and resonance to create an auditory experience that is both powerful and pleasant. The combination of great sound and outstanding performance makes the Cobra 909 Twins 4" mufflers a perfect package for those looking to upgrade their motorcycle's exhaust system.
Features:
- Satin black or chrome finish for a modern and sophisticated appearance
- Rolled inner tip with a scalloped cut inner core for a unique look
- Delivers a balanced, resonant sound enhancing the bike's acoustic profile
- Ideal for improving both sound and performance of Harley-Davidson motorcycles
- Sold in pairs (excl. for FLSB models for which they come as one muffler only for the 2-1 system)
Note for 2021+ Softail:
On 2021 and newer Softail models, Harley added extra O2 sensors on the original mufflers to meet Euro 5 standards. To prevent trouble codes, the additional sensors must be deactivated using tuning software like Vance & Hines FP4 or Dynojet Power Vision. Use part C852-744444 to plug the physical sensor connection. Local workshops and dealers may also be able to help you deactivate the sensors.
Note for 2017+ models: 2017+ Harley models may need replacement muffler gaskets if already equipped. Find replacement gaskets here.
