Frequently Asked Questions

What is the horsepower gain from installing these long tube headers on my engine?

Installing these long tube headers typically adds 15 to 25 horsepower on a naturally aspirated engine and 25 to 40 horsepower on a forced induction engine by reducing exhaust backpressure by 60 to 80 percent. The primary tube diameter is 1.5 to 1.75 inches with 16-gauge or 14-gauge steel wall thickness, and the collector size is 2.5 to 3.0 inches for optimal exhaust scavenging. For best results, pair these headers with a free-flowing exhaust system and cold air intake to gain 25 to 40 combined horsepower. The headers include provisions for oxygen sensor bungs and EGR connections so factory emissions equipment bolts directly in place. Header wrap or ceramic coating reduces underhood temperatures by 50 to 100 degrees Fahrenheit and protects the tubes from corrosion.

Will these full-length headers clear my vehicle's steering shaft and oil pan?

These full-length headers are engineered with vehicle-specific clearances for the steering shaft, oil pan, starter, and frame rails on their intended applications. The primary tubes are computer-designed to snake around the steering shaft with 0.5 to 1.0 inches of clearance at the tightest point. Installation typically takes 4 to 8 hours and requires basic hand tools, jack stands, and penetrating oil for stubborn manifold bolts. Some vehicles require unbolting the motor mounts and lifting the engine 1 to 2 inches for clearance on the driver's side header. The included header gaskets should be torqued to 15 to 20 foot-pounds in a crisscross pattern starting from the center bolts. After installation, verify at least 0.25 inches of clearance between the header tubes and all steering, braking, and suspension components at full suspension travel.

Do these stainless steel headers include the gaskets and bolts needed for installation?

These stainless steel headers include high-quality multi-layer steel or composite header gaskets rated for continuous exhaust temperatures up to 2,000 degrees Fahrenheit. The included bolts are grade 8 or stainless steel with an integrated thread-locking patch that prevents loosening from thermal expansion and vibration. The collector bolts and gaskets for connecting to the existing exhaust system are also included in this kit. Apply anti-seize compound to the header bolts and torque them to the manufacturer's specification of 15 to 20 foot-pounds. The header bolts require retightening after three to five heat cycles as the gaskets compress and seat fully during the initial 500 miles of driving.

What tools are needed to install this (CA) HEADERS PORT in my vehicle at home?

Installing this (CA) HEADERS PORT at home requires basic automotive hand tools including a socket set, combination wrenches, screwdrivers, and a torque wrench capable of measuring 10 to 100 foot-pounds. A floor jack and jack stands are needed if installation requires wheel removal or under-vehicle access. Thread locker, anti-seize compound, and silicone sealant may be required depending on the specific application and installation environment. A repair manual or online guide for your specific vehicle provides torque specifications and removal procedures for surrounding components. Most DIY installations of this (CA) HEADERS PORT take 1 to 4 hours depending on accessibility and experience level.

Does this (CA) HEADERS PORT require any modifications to the vehicle for proper fitment and operation?

This (CA) HEADERS PORT is designed for direct bolt-on installation in most compatible vehicles without requiring cutting, drilling, or permanent modifications. Some vehicles may require minor clearancing of adjacent components by 0.125 to 0.250 inches for proper clearance. Always perform a test fit before final assembly to verify the (CA) HEADERS PORT clears all surrounding components including brackets, hoses, and wiring harnesses. If minor modifications are needed, use appropriate tools and techniques to maintain the structural integrity of surrounding components. The (CA) HEADERS PORT is designed to be fully reversible, allowing the vehicle to return to stock configuration if the component is removed.
