Deep Drone Muffler

The Flowmaster 524703 70 Big Block muffler produces a deep drone that is not aggressive, suitable for drivers who prefer a quieter drive. It is especially ideal for powerful vehicles with a heavy-duty capacity. It is affordable and guaranteed to add value to your vehicle for years.

Long Case Design

The long case design helps it process high volumes of exhaust flow for heavy and powerful vehicles. It is suitable for tow vehicles and heavy trucks that need such power with minimal noise levels.

Delta Flow Technology

The muffler is designed with Flowmaster's exclusive Delta Flow technology that ensures an unrestricted flow of exhaust gases with minimum interior resonance. This makes for increased horsepower, reduced interior noise and optimal performance.

Improved Fuel Economy

Large exhaust volumes with unrestricted flow help to save up on fuel. The Flowmaster 524703 70 Big Block II muffler is made to process such huge volumes for large trucks.

Available in Two Options

The muffler is available in two finishes: aluminized steel and stainless steel. Both are high-quality, rust and corrosion resistant and will add value to your vehicle for years.

Fully MIG Welded

The muffler is fully MIG welded for super strength. It will withstand years of weather and road abuse to retain its strength and toughness for years.

Manufacturer's Warranty

Flowmaster guarantees that your muffler is of excellent quality and will serve you to satisfaction. For every purchase, you are provided with a limited lifetime warranty for the stainless steel and a three-year warranty for the aluminized steel muffler.
