Description
Overview
The Flowmaster Chevrolet, Pontiac (5.7) Exhaust System Kit delivers the classic look of a traditional dual exhaust with all the performance advantages of a genuine Flowmaster cat-back exhaust system. Built around the popular American Thunder series, this catback exhaust pairs a 3.00-inch mandrel-bent aluminized steel inlet tube with a large-case 80 Series Cross-flow performance muffler to produce a deep, powerful voice that lets your 5.7L make itself heard. If you’ve been searching to shop for exhaust upgrades that combine muscle-car sound with real drivability, this performance exhaust hits the mark.
Sound & Performance
American Thunder systems are engineered to deliver a moderate to aggressive exterior tone paired with a mild-to-moderate interior tone, so you get an assertive presence on the street without unwanted drone in the cabin. As with every Flowmaster exhaust system, the benefits reach beyond sound: expect improved throttle response, added power, and better mileage from this complete car exhaust upgrade. Whether you’re comparing a Flowmaster against a Borla exhaust, Corsa exhaust, MagnaFlow exhaust, or a Walker exhaust, this kit gives you a proven, purpose-built performance exhaust designed for the enthusiast.
Design & Fitment
This dual-out cat-back system flows from the 3.00-inch inlet into the crossflow muffler and out through dual 3.00-inch mandrel-bent tailpipes that exit at the rear. Each exhaust pipe is finished with dual 3.00-inch polished stainless steel tips for a muscular look to match the sound. The system mounts to the factory hanger locations and uses U-Bolt clamping for a straightforward, easy installation, and it includes all necessary parts and hardware to complete the job. This is a 2WD, CARB (California) compliant configuration.
