Review FLOWMASTER Cat back System Dor Kit Aggressive Sound fits OUTLAW

The Flowmaster 817740 Cat-Back 409S Dor Outlaw Kit is an aggressive aftermarket exhaust system designed to deliver a powerful and unique sound for your vehicle. This Cat-Back exhaust system is part of Flowmaster's 409 series, which is known for its bold and distinctive sound.

The kit includes all the necessary components to replace your vehicle's stock exhaust system with the high-performance 409S system. The system is a catalytic converter back exhaust, meaning it starts from the catalytic converter and goes all the way to the tip of the exhaust.

The 409S Dor Outlaw Kit features 409S mufflers, which are specifically designed to produce a deep and aggressive exhaust note. These mufflers are made with a unique internal design that utilizes a series of chambered tubes and a specific number of holes to create the unique sound. The mufflers also have a polished stainless steel tip, which not only looks great but also adds to the exhaust's overall performance by allowing spent gases to exit the system more efficiently.

The exhaust system is made of mandrel-bent stainless steel tubing, which ensures a smooth exhaust flow and reduces the risk of exhaust leaks. The stainless steel construction also ensures a long-lasting and durable exhaust system that can withstand the elements and the rigors of daily driving.

The 409S Dor Outlaw Kit also includes high-performance exhaust clamps that securely hold the exhaust system in place. These clamps are designed to provide a tight seal and prevent exhaust leaks, ensuring that your exhaust system performs at its best.

In summary, the Flowmaster 817740 Cat-Back 409S Dor Outlaw Kit is an aggressive aftermarket exhaust system that delivers a powerful and unique sound. Made of mandrel-bent stainless steel tubing and featuring 409S mufflers, this exhaust system is designed for durability and performance. With its polished stainless steel tips and high-performance exhaust clamps, this exhaust system is a great choice for anyone looking to add some personality and power to their vehicle.
