Description

When factory performance and decibel levels just aren’t enough, nothing unleashes your ride’s stifled power and sound like a premium Flowmaster muffler, like the 40-Series Delta Flow. This muffler features Flowmaster’s patented “Delta Flow” technology, consisting of numerous “delta generators” that increase scavenging and, thus, performance. As a byproduct, the 40-Series Delta Flow produces a louder and deeper tone; however, this muffler isn’t as extreme as others in Flowmaster’s lineup. The Delta Flow 40-Series is the quietest of the dual-chamber 40-series mufflers, reducing in-cab resonance for a comfortable driving experience. The 40-Series Delta Flow features a mig-welded aluminized or 409SS stainless steel construction, providing exceptional strength and corrosion resistance. While more expensive, the stainless steel variant will outlast the aluminized steel model in most conditions, specifically rust-prone areas. No matter the application, Flowmaster makes a muffler for you! The 40-Series Delta Flow mufflers come with 2.5 to 3.5-inch inlet and outlet pipes in center, dual, and offset positions to ensure the best fitment with factory-level clearances with the chassis. To bolster noise level and performance, you can’t beat the classic “Flowmaster” sound!
