One of the easiest ways to legally improve performance and economy on virtually any vehicle is to upgrade the stock Cat-Back Section. Bassani's Street Thunder Series Cat-Backs produce significant performance increases over stock systems. These systems emit a deep baritone exhaust note, somewhat louder than stock. They feature large diameter tubing and a full welded case muffler with high temperature E-glass packing to create maximum power and produce their aggressive rumble. Note: Upgrading Cat-Back sections does not affect factory warranties or emissions standards. All Bassani Products are covered by a Lifetime Warranty! Stainless Steel Construction! Polished Stainless Steel Tips Included! Includes Mandrel Bent Tubing, A High Flow Muffler(s) And All Installation Hardware! High-Temp E-Glass Packing Is Guaranteed Not To Blow Out Or Deteriorate! Aggressive Rumble!
