Dual Extreme Cat-Back Exhaust System

It is incredible how much power your Chevrolet Silverado 1500 can take with this Gibson 65637 Dual Extreme Cat-Back Exhaust. This exhaust will increase your horsepower and torque in the rpm range, giving you the ultimate performance, and a deep, aggressive sound. The superflow muffler ensures there is zero restriction as the mandrel-bent tubing allows smooth and fast movement of gases. This exhaust system is street legal in all states.

Aluminized heavy duty or stainless steel tubing

The exhaust is available in two choices; aluminized heavy duty and stainless steel tubing. Each of the choices comes with polished dual T304 stainless steel clampless tips. Whichever choice you make, you can be sure it will last you long, and even better both the aluminized and stainless tubing are rust-resistant.

Baffled and chambered Superflow muffler

The exhaust system has a baffled and chambered superflow muffler which has only as low as 5% restriction of flow. This is against the usual 34% restriction with stock mufflers and 20% with most aftermarket mufflers. With this type of muffler, you can be sure of a continuous improvement in Chevrolet Silverado 1500 performance.

Mandrel bent tubing

Gibson 65637 Dual Extreme Cat-Back Exhaust features mandrel-bent tubing. Such tubings are meant to reduce restriction and to ensure a smooth and fast flow of gases. The bends will also not crack or kink like the usual bends and this will ensure longer durability.

Increased fuel economy

Besides performance and sound improvement, this exhaust system will also improve your fuel economy especially when at cruising speed.

Dyno tuned

This exhaust system is dyno tuned for the specific application and this is to ensure it offers maximum Chevrolet Silverado 1500 performance. It is also tested being released into the market to ensure it meets all the requirements.
