Autosports Manufacturer · Meizhou, China
OUCHI engineers and manufactures high-performance exhaust systems for Porsche 911, Audi R8, Jaguar F-Type and more — combining motorsport-grade materials with obsessive attention to fitment, sound and finish.
About Us
OUCHI (Ouchi Auto Technology, Meizhou) was founded in 2023 and has grown into a specialized manufacturer of premium performance exhaust systems for European supercars. Our production facility — launched in 2025 — is equipped for the full process in-house: CAD design, CNC fabrication, hydraulic tube expansion, and hand TIG welding in both stainless steel and titanium.
Every system we ship is built against a real order with a real fitment target. We don't stock generic parts; we engineer for the car. That's why our dealer and tuning-shop partners around the world trust OUCHI as a long-term manufacturing partner, not just a supplier.
Grade-5 (Ti-6Al-4V) titanium and 304 stainless steel, graded and traceable for every production batch.
Hydraulic tube expansion, mandrel bending, precision TIG welding, and CNC-machined flanges and tips.
Fitment-checked on jigs, pressure-tested, and surface-finished before every shipment.

Every system starts in CAD — pipe routing, ground clearance, heat management and valve placement are engineered against the real chassis, not copied.
Mandrel bending keeps consistent pipe diameter through every curve. Hydraulic tube expansion produces perfect slip joints for leak-free assembly.
Experienced welders produce full-penetration, back-purged welds on titanium — the kind of welds that look as good inside as outside.
Fitment check on jigs, weld inspection, surface finishing and foam-protected export packing. Photos and video of your system before it ships.

FAQ
We work with tuning shops, distributors and brand partners worldwide. Individual enthusiasts are welcome to inquire — we'll connect you with a partner in your region when available.
Titanium (GR5) is significantly lighter and gives the signature burnt-tip look; 304 stainless is more budget-friendly and extremely durable. Both are built on the same jigs to the same fitment standard.
Yes. ODM is a core part of our business — laser-etched logos, custom packaging and private-label programs are all available.
Stock-configured systems usually ship within 2–3 weeks. Custom or first-time fitments take longer due to jig and prototype development — we confirm the schedule with your quote.
We ship by express air or sea freight with full export documentation. Duties and taxes depend on your country — we'll help you estimate them before ordering.
