Flowmaster 818169 American Thunder Cat-Back Exhaust System

This Flowmaster® American Thunder cat-back exhaust system is for the 2021-2026 Ford F-150 with the 2.7, 3.5 or 5.0-liter engine or the 3.5L PowerBoost models. This system is manufactured using durable 409 stainless steel tubing and is mandrel bent for better exhaust gas flow.

Backed by Flowmaster's Lifetime Limited Warranty.
