Frequently Asked Questions
How do Speed Engineering headers improve the performance of LS and LT swaps?
Speed Engineering headers are designed to improve exhaust flow and reduce backpressure, resulting in increased horsepower and torque. They ensure better throttle response and overall engine performance.
Why are long-tube headers recommended for performance applications?
Long-tube headers provide superior exhaust scavenging, leading to enhanced airflow and higher power output at elevated RPMs. They are ideal for maximizing performance in engine swaps.
How do turbo headers benefit LS/LT engine swaps?
Turbo headers are designed to optimize exhaust flow for turbocharged setups, improving spool times and increasing overall power output. They ensure efficient routing of exhaust gases to the turbocharger.
Why are stainless steel headers preferred for high-performance builds?
Stainless steel headers are highly durable, resistant to corrosion, and capable of withstanding high temperatures. They maintain their structural integrity and appearance over time, making them ideal for performance applications.
