Q: How often should shock absorbers be replaced?

A: It is recommended to inspect and replace them every 40,000–60,000 km. Replace immediately if there is oil leakage, abnormal noise, poor handling, or longer braking distance.

Q: Do I have to replace them in pairs?

A: It is recommended to replace them in pairs on the same axle to ensure consistent damping and avoid vehicle deviation or uneven handling.

Q: Do I need a four-wheel alignment after installation?

A: Four-wheel alignment is recommended after replacement to ensure correct tire angles, extend service life, and improve driving performance.

Q: What’s the difference between Bilstein shocks and ordinary ones?

A: Bilstein adopts German original equipment standard technology and high-quality materials, with stronger pressure resistance, longer service life, and better balance of comfort and handling.

Q: Will exhaust modification affect vehicle inspection?

A: We offer China 5 / China 6B compliant catalytic converter exhausts that meet emission regulations and can pass regular vehicle inspections. For sound wave versions, please comply with local noise management regulations.

Q: Is drilling or cutting required for installation?

A: All exhausts are designed for direct OE fitment, no drilling or cutting needed. They can be directly replaced with original parts and installed at any regular repair shop.

Q: What is the material and service life of the exhaust?

A: Made of high-quality stainless steel/titanium alloy, it is high temperature and corrosion resistant. It comes with a 1-year warranty under normal use and can last 5-8 years.

Q: Will carbon fiber parts turn yellow or fade?

A: The surface is coated with high-transparency scratch-resistant UV clear coat, which effectively resists UV and rain erosion. It will not turn yellow or fade for 3-5 years under normal use.

Q: Is drilling required for installation? Are they secure?

A: CNC precision cut to perfectly match the body contour. Most products are fixed with original mounting points or 3M tape + clips, ensuring firmness without looseness.

Q: How much lighter are carbon fiber parts compared to original parts?

A: Carbon fiber parts are 30%-40% lighter than original metal/plastic parts, effectively reducing vehicle weight and improving handling and power response.
