    More performance with a powerful sound.

    Gain 10 to 15 horsepower to the rear wheels by adding these high-performance mufflers. Manufactured in the USA using the highest quality materials and the latest technology—the standard in high-performance exhaust. The “Delta Flow” mufflers have a milder tone that generates a powerful sound outside the vehicle with a lower interior resonance, while improving torque and horsepower. These extreme high-flow mufflers will give your vehicle that powerful muscle car sound that you are looking for.
