DynoVox Header Outstanding Features:

  • Material: Crafted from premium 304 stainless steel, these headers offer exceptional durability and resistance to harsh driving conditions. The laser-cut, 3/8-inch-thick steel flanges ensure a precise, leak-proof seal.
  • Performance: Engineered specifically for Chevrolet engines, these headers provide a noticeable boost in horsepower, particularly from idle to mid-range RPMs, enhancing overall vehicle performance and efficiency.
  • Installation: Designed for easy installation, these headers can be bolted directly in place of your factory headers. For optimal results and a seamless fit, professional installation is highly recommended.

Why upgrade the exhaust manifold?

Upgrading the exhaust manifold to high-performance headers offers several advantages:

  • Increased Performance: Aftermarket headers improve exhaust flow, reducing backpressure and enabling the engine to produce more horsepower and torque.
  • Enhanced Durability: Headers are often constructed from high-quality materials like stainless steel, offering better resistance to heat and corrosion than stock manifolds.
  • Improved Fuel Efficiency: By optimizing exhaust flow, headers can contribute to better fuel economy under certain driving conditions.
  • Aggressive Sound: Upgraded headers often produce a deeper and more aggressive exhaust note, enhancing the driving experience.
  • Customization: Headers can be tailored to specific performance goals, such as improving low-end torque or maximizing high-RPM power.

Frequently asked questions
Do exhaust headers increase HP?
You can use these exhaust headers on the race track or the streets, as they generally provide more significant boosts in horsepower and torque than shorties. Long tube performance headers see the most performance gains in the mid-low to mid-high RPM range.
Are aftermarket exhaust headers worth it?
Beyond creating a less restrictive system and boosting performance, headers have another advantage over manifolds, making them a worthwhile upgrade for many car owners. Headers can produce a scavenging effect. When a pulse of exhaust leaves a header tube into a collector, it creates a negative wave of pressure.
What size headers for 350 SBC?
For racing applications such as circle track cars, a 350 engine will commonly be outfitted with 1 3/4 or 1 7/8 inch primary tube size and a 3 inch or 3 1/2 inch collector
What does a exhaust header do for a car?
Like exhaust manifolds, headers are designed to route exhaust gases from the engine to the exhaust system. The primary difference is that headers create less exhaust backpressure than exhaust manifolds, thereby allowing the engine to breathe more easily. Headers are usually made from thin-walled stainless steel tubing.
