Engineered toOut Perform Everything.
Scan. Design.Print. Build.
One shop, start to finish. High-end exotic custom exhaust work and 3D-printed parts, engineered, manufactured and fitted in-house.
Custom Exhaust Fabrication
Titanium and stainless systems, headers, X-pipes and rear sections for exotic and high-end cars, welded to aerospace standards and tuned for sound and flow.
Metal & Composite 3D Printing
Production-grade parts in titanium, Inconel, aluminum and stainless steel. Geometry that conventional fabrication can't reach.
3D Scanning
High-resolution capture of vehicles, components and assemblies. The scan becomes the exact reference for every part that follows.
CAD & Reverse Engineering
Concept to production-ready models. Rebuild or redesign housings, ducting, brackets, aero and mechanical parts with exact fitment.
Contract Fabrication
Fabrication labor and CAD support for builders and shops with projects that need an extra set of certified hands.

- STEP 1ScanWe capture the car or part so every dimension is real, not guessed.
- STEP 2EngineerCAD design and flow simulation, built around your fitment and goals.
- STEP 3ManufactureMetal printed, welded and finished in-house.
- STEP 4FitTest-fit and install on the car, ready to drive.
Built in the shop.Proven on the road.
Every header, X-pipe and printed part starts as a scan of the actual car and ends as a finished part on it.
PrintedParts.
Rival X-Pipe
True X-merge geometry developed through CFD for better scavenging, balanced pressure and sharper throttle response.
964 Step Headers
Equal-length, stepped primaries into a precision collector. Built to hold gas velocity and pulse timing across the rev range.
964 OEM-Style Tips
Keep the factory 964 look with a custom exhaust. Slim-fit sleeves slide over your tips and sit clean in the stock valance.
3-1 Merge Collector
A 3D-printed 3-into-1 collector with a smooth internal merge, ready to weld into your custom headers.
Built from passion.Refined by precision.
Aerospace discipline.Exotic-car obsession.
Rival Autohaus was founded by Paul, a fabricator with a background in aerospace propulsion assembly and years of hands-on work on Porsche, Lamborghini and Ferrari platforms.
That standard carries into every job: certified welding, scan-based engineering, and parts we design, print and finish ourselves.
