The Flowmaster 40 delta flow muffler is the quietest in the Flowmaster 40 series. It uses sophisticated Gen II delta flow technology to improve your vehicle's performance. It has a single center outlet and a single offset inlet for optimum exhaust flow and boosted engine performance.
The muffler absorbs internal resonance to reduce interior drones. This makes the inside of your vehicle quieter for a more peaceful ride.
With an unrestricted flow of exhaust gases, your engine functions at optimal capacity to give the best it can. This means improving your engine's horsepower, saving up on gas mileage, and maintaining a healthier engine.
The Flowmaster 40 delta flow muffler features a large chamber design to handle large exhaust volumes and emissions from powerful engines. The muffler is particularly ideal for heavy-duty vehicles with large exhaust volumes.
It has a black painted finish that looks great with any vehicle exterior. The coat also prevents scratches and corrosion to boost the muffler's durability.
The mufflers are MIG welded for durability. Every inch is carefully crafted for strength to last years in all road and weather elements.
They are available in both stainless steel and aluminized steel. Both mufflers are durable and tough, and your choice will depend on the needs of your exhaust system.
Flowmaster provides a limited lifetime warranty for the stainless steel muffler and a 3-year warranty for the one made from aluminized steel. It is a guarantee that the muffler is worth your money in all aspects, including quality, craftsmanship, and performance. If you need any help or further information about your warranty, feel free to get in touch with PartCatalog.
Your muffler is proudly made in the USA using local materials, technology, and labor. Your purchase helps to create jobs for thousands of Americans every year.
