Description
Overview
The Flowmaster American Thunder Crossmember-Back Exhaust System Kit is engineered specifically for the 1966-1967 Ford Fairlane equipped with the 289, 390, or 427 engine. Built to maximize flow and deliver the unmistakable rumble of a classic muscle car, this complete exhaust system transforms both the sound and the performance of your Fairlane while bolting into a 2WD chassis with all the parts, hardware, and instructions needed to finish the job.
Constructed from 2.50-inch mandrel-bent 16 gauge aluminized steel tubing, this exhaust system is designed to maximize exhaust flow from the crossmember back. The included H-pipe crossover equalizes exhaust pressures between the banks and eliminates backrap on deceleration, giving you cleaner throttle response and a more refined tone whether you’re cruising or getting on the gas.
Sound & Performance
At the heart of this performance exhaust are the large-case Super 50 Series mufflers (part number 52556). These mufflers deliver a deep, powerful sound with a moderate sound level that suits a street-driven classic, and they flow into mandrel-bent dual tailpipes for maximum performance. Built-in resonators keep interior resonance to a minimum, so you get the aggressive exterior note without an overwhelming drone inside the cabin.
