Description
Overview
The Flowmaster American Thunder Cat-back Exhaust System is a custom-engineered bolt-on upgrade designed specifically for 1992-1995 Chevrolet Blazer and GMC Jimmy models equipped with the 5.7L engine. Built for the driver who wants real performance without an overpowering drone, this American Thunder system delivers a mild to moderate sound level inside the cabin and a moderate, aggressive tone on the outside — all backed by the performance benefits Flowmaster is known for.
At the heart of the system is a flanged 3.00-inch mandrel-bent aluminized steel inlet pipe that flows smoothly into the legendary Super 50 Series muffler (part number 53058). This combination produces a deep, powerful tone while the mandrel-bent construction promotes efficient exhaust flow. The single 3.00-inch aluminized steel mandrel-bent tailpipe is finished with an angle-cut turn-down style tip that exits behind the right rear wheel, giving your truck a clean, purposeful look.
Key Benefits
Everything about this cat-back is designed for a straightforward, at-home installation. It uses the factory hanger locations and includes all necessary parts and hardware, along with U-bolt clamping for a secure, no-fuss fit. Because it is a true bolt-on emissions-legal system that is CARB compliant, you get the sound and performance you want while staying street-legal.

Sound and Performance
The Super 50 Series muffler strikes the ideal balance for a daily-driven truck. Inside the cabin you get a refined mild-to-moderate sound level that is comfortable on long highway drives, while outside your Blazer or Jimmy takes on a deep, moderate tone that announces its presence without becoming obnoxious. It’s the perfect middle ground for enthusiasts who want more sound and flow than stock without going all-out loud.
