The Yonristic Competition Long-Tube Equal-Length Headers unlock the true potential of the Porsche 992 GT3 and GT3 RS, delivering real motorsport performance and sound. Crafted from 304 stainless steel with full heat-shield wrap, these headers eliminate factory backpressure with long, pulse-tuned primaries and a high-flow collector, unleashing gains of +12–16 whp with 200-cell cats and up to +22 whp catless — with ECU tuning pushing total improvements to nearly +30 whp. The result is sharper throttle response, a harder mid-range pull, and a spine-tingling flat-six wail to 9,000 rpm, all in a direct bolt-on package built to withstand track punishment while elevating street presence.

Sound & Driveability

Equal length kills the uneven, phasey note of short/unequal runners. Idle settles into a richer baritone; mid-range gains a muscular, linear surge; and the top-end rips with a clean, high-frequency wail. Because pulses are synchronized and the collector does the work—not the muffler—you get aggression without drone and clarity without harshness.

Realistic Performance Gains*

Dyno results from the 992 GT3 platform with developed long-tube/equal-length headers consistently show double-digit improvements, with 200-cell catted options slightly behind catless race versions, as expected.

200-Cell HJS-style Catted Version:
+12–16 whp / +16–20 lb-ft at the wheels (≈ +15–20 hp crank).
Catless (Race) Version:
+18–22 whp / +24–28 lb-ft at the wheels (≈ +22–26 hp crank).
With ECU Calibration (on top of our headers):
Expect an additional +4–8 whp / +5–9 lb-ft, for combined gains of roughly +20–30 whp depending on catted vs. catless, fuel quality, and paired rear exhaust. (Community and vendor data on GT3 header + tune packages support these ranges.)

*Actual results vary with dyno type, ambient conditions, OPF/GPF presence, rear-section choice, and calibration strategy. Ranges above reflect reputable vendor dynos and community testing on the 992 GT3 platform.

Why It Works

Long primaries and equal length time the negative pressure wave to arrive as the exhaust valve opens on the next cycle—this pulls spent gases out and helps draw the intake charge in. The longer, smoother path reduces backpressure where the GT3 breathes hardest (upper mid-range to redline), so you feel earlier torque, a stronger sweep to 9k, and cleaner gear-to-gear transitions.
