Doug's headers are constructed to proper size and length using high-quality, hand-built, mandrel-bent materials. By incorporating this upgrade into your classic Chevelle, you will experience a noticeable increase in horsepower and torque, while also reducing pumping losses and effectively removing all exhaust from the cylinders.
