🟦 New Part – Race Exhaust & Turbo Performance Upgrade (86–87 Turbo Buick)
Why You Want It
Because race builds demand race airflow. These headers dramatically improve exhaust scavenging and eliminate the factory bottleneck, allowing the turbo to spool harder, faster, and more efficiently under high boost. Designed for serious power levels, this setup supports higher horsepower while reducing exhaust restriction and heat concentration at the ports. If you’re chasing ETs, top-end power, or building a high-boost combination, this header kit is a foundational upgrade that lets your turbo and engine operate at their full potential.
Installation Note
Before installation, we strongly recommend blowing out all tubing with compressed air to remove any manufacturing or shipping debris. This ensures nothing enters the turbo or engine during initial startup.
