 Detailed Description
Flowmaster 70 Series Big Block II Mufflers
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. The 70 Series mufflers are perfect for high performance street cars, most trucks, SUVs, RVs and tow vehicles that require quiet operations with improved sound.

♦ Best suited for truck applications - quiet operation!
♦ Features three-chamber Delta Flow Technology
♦ Constructed of 16-gauge aluminized steel
♦ Fully MIG-welded for maximum durability
