Description
Overview
The Flowmaster 70 Series Chambered Muffler is engineered for drivers who want a milder, more refined exhaust note without giving up performance. Built around Flowmaster’s proven Delta Flow® technology and an enlarged case design, this 70 Series Big Block muffler delivers improved sound control along with mileage and power gains, making it a smart upgrade for a wide range of applications.
Delta Flow® technology manages exhaust pulses to smooth out the sound while promoting efficient flow through the muffler. Paired with the larger case, the result is a mild, refined tone that stays comfortable inside the cabin and out on the highway during long hauls, all while helping your engine breathe.

A high-temperature paint finish adds an extra layer of protection where it matters most.

Please note the muffler uses new hangers, which are not included, and any exhaust tips are sold separately, so plan your installation accordingly. As a universal component, always confirm the inlet, outlet, and available space match your vehicle before purchase.
For truck, SUV, and tow vehicle owners who want the Flowmaster reputation with a mild, livable sound, the 70 Series Big Block Chambered Muffler is a durable, performance-minded choice. Add the correct hangers and your preferred exhaust tip to complete the build.
