Product Description
Upgrade your 1998–2002 Chevrolet Camaro or Pontiac Firebird equipped with the 5.7L LS1 V8 engine with the Flowmaster American Thunder Cat-Back Exhaust System, available in two tip-size variations: Part #17234 with 4.00-inch polished tips and Part #17233 with 3.00-inch polished tips. Both systems feature a large-case 80 Series Cross-Flow performance muffler and mandrel-bent 16-gauge aluminized steel tubing, delivering a deep, powerful exhaust tone with an aggressive exterior sound and a moderate interior tone.
Both variations feature a 3.00-inch inlet, dual rear-exit tailpipes, factory hanger compatibility, and included hangers, clamps, and installation hardware. Choose the 4.00-inch tips on Part #17234 for a larger, more prominent appearance, or the 3.00-inch tips on Part #17233 for a more understated finish. Both systems are backed by Flowmaster's 3-Year Limited Warranty.
