FAQ

1. How does the vacuum valve work?

The vacuum valve is actuated by engine vacuum pressure. At idle and light throttle, the valve remains closed for a quieter, more refined tone. Under hard acceleration, vacuum drops and the valve opens, unleashing the full unrestricted exhaust note — no wiring or controllers needed.

2. What are the benefits of 76mm piping over stock?

The enlarged 76mm bore significantly increases exhaust gas flow capacity versus the restrictive OEM piping, reducing backpressure downstream of the turbo and enabling higher power output — especially effective when paired with Stage 1 or Stage 2 ECU tunes.

3. Is this a direct bolt-on fitment?

Yes. This system is engineered via high-definition 3D vehicle chassis scans for a 100% direct bolt-on fitment with all factory mounting points and downpipe flanges. No cutting or welding required.

4. Are you a direct manufacturer?

Yes — as a direct manufacturer based in Guangdong, China, we eliminate middlemen to deliver premium, track-tested exhaust systems with strict in-house quality control, competitive pricing, and fully customizable finish options.
