  • Deep "Flowmaster" Tone: The Super 40 muffler offers the same great tone as the Original 40 from Flowmaster. It offers a deep, powerful tone that screams performance and turns heads.
  • Tame Interior Manners: Flowmaster's Delta Flow Technology gives the Super 40 Series muffler a much lighter interior tone. The Gen II case technology vastly reduces interior drone and resonance.
  • Improved Performance: The Flowmaster Super 40 offers improved exhaust flow and performance. Unrestricted flow is great for improved horsepower and torque.
  • For Cars & Trucks: The Super 40 is ideal for high horsepower cars and trucks. A large internal chamber is specifically designed for large volumes of exhaust flow coming from large bore modified engines.
  • Black Painted Finish: The Flowmaster Super 40 is constructed of aluminized steel and finished with a black paint for a unique look and improved durability.
  • Made in the USA - Santa Rosa, CA

The Super 40 mufflers feature Flowmaster's newest "Gen II Delta Flow" technology. Inspired by the Top Ten race muffler, the Super 40 offers the best of both worlds when it comes to performance and sound. It's perfect for high horsepower vehicles offering unmatched performance and horsepower gains. The Super 40 offers a aggressively deep rumble similar to the Super 44, with much less interior resonance and drone. It comes in a black painted finish with a 13.5"L x 10"W x 5" H case and an overall length of 19.5". For a muffler that screams that "Flowmaster" sound without overbearing interior noise, look no further than the Super 40 Series mufflers.

California Residents: Prop 65 Warning



Flowmaster mufflers are designed to work with new or existing exhaust systems. They offer slip on installation and can be welded or clamped into place. Due to the use of heavier materials,Flowmaster recommends spot welding the joints when using clamps. On some applications it will be necessary to cut or splice when adding Flowmaster mufflers to an existing exhaust system.


Flowmaster is offering a 3 year limited warranty on the aluminum Super 40 Series Delta Flow Mufflers.
