The graceful arcing lines of the Speedster Swept exhaust system follow the curved shapes of the new Fury to create a great look. They have a deep rumble that improves the sound but keeps the noise down. In fact they may have the best balance of sound and volume of any pipe we've ever made: Rich and throaty but not window rattling either. Like all Cobra's Speedsters, the Swepts include the Cobra PowerPort for increased low and mid-range power. They are equipped with full length 2.5-inch heat shields which wrap around 222 degrees and cover the 1.75-inch headpipes. Of course they also have Cobra's Limited Lifetime Warranty.
