Cobra, 4″ slip-ons with Race Pro end caps
for 2017 Touring models
These RPTs (Race Pro Tips) are 4″ diameter and expand to 4 1/2″ RPTs. The 3″ core technique is far beyond the louvered metal tubes, which enabled Cobra to engineer and use high frequency sound chattering technique in the high-flow core to enhance the lower mellow tones. The result is a muffler system that offers great sound quality without mid-range distortion or raspy irritation.
