Review WALKER EXHAUST

The Walker Exhaust 21047 is a high-performance aftermarket exhaust system designed to provide improved power and enhanced exhaust flow for select Ford, Lincoln, and Mercury vehicles. This exhaust system is manufactured with premium quality materials to ensure durability and longevity.

The Walker 21047 exhaust system is a catalytic converter-back exhaust, which means it replaces the rear sections of the exhaust system from the catalytic converter back. It features a polished stainless steel finish that not only looks great but also provides excellent protection against corrosion and rust.

One of the key features of this exhaust system is its 3-inch diameter pipe diameter, which helps to reduce backpressure and increase exhaust flow. This results in better engine performance, as more exhaust gases can be expelled from the engine more efficiently.

Another notable feature of the Walker 21047 exhaust system is its straight-through design. This design allows for unrestricted exhaust flow, which further contributes to improved engine performance by reducing exhaust restrictions and maximizing exhaust velocity.

This exhaust system also comes with a muffler that features a unique, chambered design. This design helps to reduce exhaust noise while still allowing for a more aggressive exhaust note compared to stock exhaust systems. The result is a performance exhaust system that provides both improved power and a more enjoyable driving experience.

Installation of the Walker 21047 exhaust system is relatively straightforward and can typically be completed in a few hours with basic hand tools. It is important to note that this exhaust system may require some modifications to the factory exhaust system to ensure a proper fit, such as the use of included exhaust clamps or adapters.

Overall, the Walker Exhaust 21047 is a high-quality, performance exhaust system that is designed to provide improved power, enhanced exhaust flow, and a more aggressive exhaust note for select Ford, Lincoln, and Mercury vehicles. Its durable construction, easy installation, and attractive finish make it an excellent choice for those looking to upgrade their exhaust system.
