The 70 Series Big Block Muffler uses a longer case for increased volume and added sound reduction that will still fit many applications where the wider 50 Series Big Block muffler won’t fit. The 70 Series Big Block utilizes Flowmaster’s patented Delta Flow Technology for maximum efficiency and minimum interior resonance street cars, most trucks, SUV’s, RVs and tow vehicles that require quiet operation with improved sound.
It helped me using the Truck daily, especially at night, where I must keep the sound down to the minimum when entering my neighborhood.
Flowmaster have delivered their promise in tuning down and treating the loud big block rumble. I respect such effort.
