The Flowmaster American Thunder Exhaust System is a powerful upgrade for vehicles equipped with a 5.7L engine and factory dual tailpipes. Designed to deliver a deep, aggressive exterior tone with mild interior resonance, this cat-back system boosts both performance and sound without compromising daily drivability.Built from durable mandrel-bent stainless steel tubing, this bolt-on system ensures optimal exhaust flow and long-lasting performance. At its core is the 50 Series™ HD muffler, engineered specifically for Hemi-powered applications, offering refined acoustic tuning and increased horsepower. The dual 3.00-inch tailpipes clear the factory spare tire with ease, maintaining full functionality while improving underbody flow.To complete the look, the system features large 4.00-inch black ceramic-coated tips that fill out the rear bumper cutouts for a bold, factory-integrated appearance.
