Description: Dominate the track with HPI’s high-performance exhaust manifold, specifically engineered for the high-output demands of the RX-7's turbocharged rotary engine.
Whether you are building a street beast or a dedicated time-attack machine, this manifold is designed to maximize exhaust velocity and drive large turbines with ease.
Crafted from lightweight and high-durability SUS304 stainless steel, our manifolds are built to endure the extreme EGTs (Exhaust Gas Temperatures) characteristic of the 13B engine.
By optimizing pipe length, geometry, and collector settings, we’ve achieved an ideal exhaust flow that drastically improves turbo response and top-end horsepower.
This manifold features a T04 flange, making it the perfect foundation for big-single turbo conversions.
Trusted by professionals and enthusiasts alike, HPI provides the reliability and performance needed to push your RX-7 to its absolute limits.
Key Features:
Big Turbine Ready: Equipped with a T04 flange and designed for external wastegate setups.
Rotary-Spec Durability: Premium SUS304 construction handles the intense thermal stress of high-power rotary tuning.
Precision Engineering: Optimized pipe diameters (φ50 or φ60) to suit your specific power goals and turbine size.
Ideal Flow Dynamics: Collector and pipe geometry are fine-tuned for maximum exhaust efficiency and minimal backpressure.
