For enthusiasts seeking a discreet custom touch coupled with the advantages of a Flowmaster Cat-back exhaust system, the American Thunder system tailored for the 2001-2006 (2007 Classic) Chevrolet Silverado and GMC Sierra 2500HD/3500HD with 6.0L or 8.1L engine is the ideal choice. This system, featuring a dual inlet muffler, delivers a balanced experience with a moderate interior tone and a deep, powerful exterior tone. It caters to performance enthusiasts who want their vehicle's prowess to be audibly acknowledged.
Connecting to the catalytic converter, the system incorporates a dual inlet 50 Series Big Block muffler, ensuring a robust, powerful sound without being overly assertive.
