FAQ

1. What is the difference between Catted and Catless?

The Catted version includes a high-flow catalytic converter, making it street-legal and emissions-compliant in most regions. The Catless (No Cat) version removes the catalyst entirely for maximum flow and performance — ideal for track use or regions without strict emissions regulations.

2. Will this void my warranty?

Aftermarket exhaust modifications may affect your vehicle warranty. We recommend checking with your dealer. The installation is 100% reversible — you can return to stock at any time.

3. Is professional installation required?

While the bolt-on design makes installation straightforward, we recommend having it fitted by a qualified exhaust technician for best results.

4. Are you a direct manufacturer?

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