SPDZ1 RH Race 4-2-1 Ramhorn Header – K-Swap K20 / K24 (EG, EK, DC2, DA)
Built for racers. Engineered for results.
The SPDZ1 RH Race 4-2-1 Ramhorn Header is the ultimate long-tube solution for serious K-Swap builds. Whether you’re pushing a high-revving K20 or a torque-heavy K24, this header is engineered to deliver unmatched throttle response, increased horsepower, and cleaner exhaust flow across the powerband — all while maintaining proper fitment in your EG, EK, or DC2/DA chassis.
Designed for serious performance and fabricated with race-grade materials, the SPDZ1 Ramhorn Header outclasses the competition with thicker flanges, improved welds, premium gaskets, and enhanced packaging protection — because quality matters from unboxing to redline.
Key Features:
- True 4-2-1 Tri-Y Ramhorn Design: Engineered for superior exhaust scavenging, torque delivery, and high-RPM power.
