Engineered for enthusiasts who want a deep, aggressive exhaust tone outside the truck while maintaining a comfortable moderate interior sound, this premium performance exhaust delivers the unmistakable Flowmaster rumble without sacrificing everyday drivability. The system features mandrel-bent 16-gauge aluminized steel tubing paired with a specially engineered Super 40 Series chambered performance muffler to improve exhaust flow, enhance throttle response, and provide the powerful sound that performance truck owners expect. Designed as a direct bolt-on replacement, the kit utilizes factory hanger locations and includes all required hardware for a hassle-free installation. Dual exit options allow the tailpipes to exit behind the rear wheels for towing applications or straight out beneath the rear bumper for a bold, muscular appearance, while polished 304 stainless steel exhaust tips provide the perfect finishing touch.\u003c\/p\u003e\n\u003ch2\u003e\u003cstrong\u003eKey Features\u003c\/strong\u003e\u003c\/h2\u003e\n\u003cul\u003e\n\u003cli\u003eFlowmaster American Thunder Cat-Back Exhaust System\u003c\/li\u003e\n\u003cli\u003eSpecially designed Super 40 Series chambered performance muffler\u003c\/li\u003e\n\u003cli\u003eMandrel-bent 16-gauge aluminized steel tubing for improved exhaust flow\u003c\/li\u003e\n\u003cli\u003eAggressive exterior exhaust tone with a comfortable moderate interior sound level\u003c\/li\u003e\n\u003cli\u003eDual 2.50-inch tailpipes with optional rear or side exit configuration\u003c\/li\u003e\n\u003cli\u003eLarge 3.00-inch polished 304 stainless steel exhaust tips\u003c\/li\u003e\n\u003cli\u003eDyno tuned to maximize performance and exhaust efficiency\u003c\/li\u003e\n\u003cli\u003eDirect bolt-on installation using factory hanger locations\u003c\/li\u003e\n\u003cli\u003eIncludes clamps, hangers, mounting hardware, and installation components\u003c\/li\u003e\n\u003cli\u003eCompatible with both 2WD and 4WD models across all wheelbases\u003c\/li\u003e\n\u003cli\u003eEmissions legal cat-back exhaust design\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch2\u003e\u003cstrong\u003eBenefits\u003c\/strong\u003e\u003c\/h2\u003e\n\u003cul\u003e\n\u003cli\u003eProduces the iconic Flowmaster performance exhaust sound with improved driving excitement.\u003c\/li\u003e\n\u003cli\u003eHelps improve exhaust flow for enhanced throttle response and overall engine efficiency.\u003c\/li\u003e\n\u003cli\u003eOffers versatile dual exit routing to match towing needs or a custom performance appearance.\u003c\/li\u003e\n\u003cli\u003ePremium aluminized steel construction delivers long-lasting durability and corrosion resistance.\u003c\/li\u003e\n\u003cli\u003ePolished stainless steel exhaust tips provide a clean, high-performance finish.\u003c\/li\u003e\n\u003cli\u003eBolt-on design minimizes installation time without requiring extensive modifications.\u003c\/li\u003e\n\u003cli\u003eBacked by Flowmaster's 3-Year Limited Warranty for added confidence and long-term value.\u003cbr\u003e\n\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch2\u003e\u003cstrong\u003eProduct Specifications\u003c\/strong\u003e\u003c\/h2\u003e\n\u003cul\u003e\n\u003cli\u003ePart Number: 17417\u003c\/li\u003e\n\u003cli\u003eProduct Type: Cat-Back Exhaust System\u003c\/li\u003e\n\u003cli\u003eExhaust Series: American Thunder\u003c\/li\u003e\n\u003cli\u003eSound Level: Aggressive exterior \/ Moderate interior\u003c\/li\u003e\n\u003cli\u003ePipe Material: 16-gauge aluminized steel\u003c\/li\u003e\n\u003cli\u003ePipe Finish: Aluminized silver\u003c\/li\u003e\n\u003cli\u003eMain Pipe Diameter: 2.50 inches\u003c\/li\u003e\n\u003cli\u003eInlet Diameter: 3.00 inches\u003c\/li\u003e\n\u003cli\u003eMuffler Series: Super 40 Series\u003c\/li\u003e\n\u003cli\u003eMuffler Type: Chambered\u003c\/li\u003e\n\u003cli\u003eMuffler Material: Aluminized steel\u003c\/li\u003e\n\u003cli\u003eMuffler Finish: Black high-temperature coating\u003c\/li\u003e\n\u003cli\u003eMuffler Dimensions: 10.00 in. long x 10.00 in. wide x 5.00 in. high\u003c\/li\u003e\n\u003cli\u003eTailpipe Configuration: Dual\u003c\/li\u003e\n\u003cli\u003eExit Style: Dual Out Rear or Dual Out Side\u003c\/li\u003e\n\u003cli\u003eExhaust Tip Quantity: 2\u003c\/li\u003e\n\u003cli\u003eExhaust Tip Material: 304 stainless steel\u003c\/li\u003e\n\u003cli\u003eExhaust Tip Finish: Polished\u003c\/li\u003e\n\u003cli\u003eExhaust Tip Diameter: 3.00 inches\u003c\/li\u003e\n\u003cli\u003eExhaust Tip Length: 13.00 inches\u003c\/li\u003e\n\u003cli\u003eExhaust Tip Shape: Round\u003c\/li\u003e\n\u003cli\u003eExhaust Tip Style: Rolled edge, angle cut, single wall\u003c\/li\u003e\n\u003cli\u003eClamps Included: Yes\u003c\/li\u003e\n\u003cli\u003eHangers Included: Yes\u003c\/li\u003e\n\u003cli\u003eMounting Hardware Included: Yes\u003c\/li\u003e\n\u003cli\u003eCatalytic Converters Included: No\u003c\/li\u003e\n\u003cli\u003eDrive Compatibility: 2WD and 4WD\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch2\u003e\u003cstrong\u003eInstall Difficulty Level\u003c\/strong\u003e\u003c\/h2\u003e\n\u003cp\u003e\u003cstrong\u003eEasy.\u003c\/strong\u003e This direct-fit, bolt-on exhaust system is designed to install using the factory mounting locations with no welding required under normal installation.
