Key Benefits
At the heart of the 70 Series is Flowmaster’s Delta Flow® technology, which manages exhaust flow to reduce interior resonance and drone while promoting efficient scavenging. The enlarged case works alongside this technology to control sound and support power and efficiency gains. The result is a muffler that keeps things mild and comfortable for street driving while still standing up to the demands of towing and high-output applications.
Durability is built in. The 70 Series is constructed from 16 gauge aluminized steel and fully MIG welded for maximum strength and long-term reliability. A high-temperature paint finish helps the muffler withstand the heat and harsh conditions of everyday exhaust duty, so it holds up mile after mile.
