Cobra Exhaust Power Pro 2 into 1 Chrome Yamaha V-Star 1100 Custom 1999-2003 2417 Cobra once again leads with innovation. Our new PowerPro, 2-into-1 pipe features our unique 222 collector heatshield. Its an industry first because it does more than protect; it cleans up and streamlines the chunky collector area that other 2-into-1 pipes ignore, thus completing a clean seamless appearance from the head pipes to the muffler. We also developed our proprietary internal cooling technology into the muffler area to prevent bluing. That means the superb custom craftsmanship and high-quality finish on the PowerPro will remain. Weve also taken proven Cobra exhaust tuning technology to new heights with the PowerPro 2-into-1 pipe producing class-leading horsepower.
