Increased power, torque and mileage are vital for today's trucks, SUVs and RVs. That's why Flowmaster makes a 50 Series Big Block Muffler that cranks-out extra force at the pedal for towing. Plus, the efficiency of the Flowmaster 50 series Big Block reduces under-hood temperatures, lengthening the life of critical engine components.
Don't forget the famous Flowmaster sound you get with the 50 Series Big Block Muffler. It's a milder tone-quieter than the 40 Series-but with plenty of the famous Flowmaster roar. Interior resonance is greatly reduced by the large H-chamber design, which not only makes for a calmer cab but also handles your big engine under heavy loads.
The 50 Series Big Block Muffler boasts the quality construction you'd expect from Flowmaster. Each Flowmaster Muffler is built with 16-gauge aluminized steel for corrosion resistance and fully mig-welded for maximum durability. Best yet, your Flowmaster 50 Series Big Block Muffler boasts a 3-year warranty.
