    Features

    Description

    All the power and performance of Flowmaster's muscular mufflers without the roaring interior resonance-that's the idea behind their 40 Series Delta Flow Muffler. It's the ideal pick for late-model performance cars that want powerful exterior tone while enjoying a quieter ride.

    At the heart of the 2-chamber design is Flowmaster's exclusive Delta Flow technology. This innovative engineering utilizes precision-placed deflectors that not only mute interior sound, they fuel increased exhaust scavenging for the most possible power.

    Also ideal for dual exhaust cruisers, the Flowmaster 40 Series Delta Flow Muffler boasts the quality construction you'd expect from Flowmaster. Each Flowmaster muffler is built with 16-gauge aluminized steel or stainless steel for corrosion resistance and fully mig-welded for maximum durability. Best yet, your Flowmaster 40 Series Delta Flow Muffler boasts a 3-year warranty on aluminized and a Limited Lifetime Warranty on stainless steel.

    Louder than I anticipated (but not too loud). Wonderful sound overall. Very satisfied with my purchase!

    Great throaty sound, not too loud, little cab noise but nothing that's bothersome. Had it installed at muffler shop to insure proper installation. Really opens up when I get on it. Very happy with price and quality.

    Solid construction and good fit because.....its universal! Most of my exhaust is custom since the original rotted out so it sits only a foot off the cat pipe and turned down....if a good rumble is what your after this muffler will suffice but your scenario may differ.
