Porsche 992 GT3 / GT3RS - Competition Long-Tube Header VANTA - Yonristic Performance

Premium Porsche 992 GT3 Long-Tube Header for Optimal Performance

Built to win. Tuned to sing. The 992 GT3 and GT3 RS are benchmark track cars, but their factory header assemblies are a compromise—short primary runners, dense packaging and high-cell catalysts that raise backpressure, flatten mid-range response, and mute the glorious character of the 4.0-liter Mezger-line flat-six. Our Competition Long-Tube Equal-Length Headers remove those bottlenecks. Each cylinder sees a true, matched primary length that times pressure waves at the collector for strong scavenging, quicker cylinder emptying, and a broader, cleaner power band. The result is a sharper throttle, a harder pull from 4,000 rpm to redline, and the razor-clear motorsport timbre GT3 owners crave—without the brittle rasp.

Design & Construction

Architecture: long-tube, truly equal-length primaries merging into a high-efficiency collector for pulse-timed scavenging and reduced reversion.

Material: AISI 304 stainless steel only (no mix-and-match)—chosen for durability, heat resistance, and stable acoustic character.

Thermal Management: full integrated heat-shield wrap to protect surrounding components and lower under-body temps.

Manufacturing: CAD/3D scanned for millimetric fit; CNC-machined head flanges ; back-purged TIG welds with smooth internal transitions to keep velocity high.

Fitment: 992 GT3 and 992 GT3 RS (all years). Direct bolt-on to factory locations.

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.
