AD-01-HDR · 3-into-1 headers Three into one, per bank.

One header per bank. Three primaries run from three-bolt port flanges into a collector with a lambda sensor boss and a V-band outlet for the optional sport catalyst. Available separately or as part of the complete AD-01.

V-band to the catalyst, catalyst on the printed bracket.

The collector's V-band carries the catalyst, and the printed header bracket takes its weight on the engine side. The lambda sensor sits in the collector boss, ahead of the catalyst.

AD-01-MNT · Printed rear mount 50 g where 2.27 kg used to be.

In stainless steel, the complete AD-01 is 45% lighter than the factory system, in either design. The rear mount shows how: 50 g of printed metal replaces 2.27 kg of factory mounting hardware and straps. Developed around a 3D underbody scan, it attaches at the original mounting points.

The 50 g and 2.27 kg figures compare the rear mounting assembly alone.

What does it cost?

In stainless steel, the headers are US$6,800, the cat-back US$8,500 and the full system US$15,300. Titanium adds US$1,500 and Inconel US$3,000 per part. 200-cell GESI sport catalysts add US$1,700; tips are US$500, or US$800 for the printed design. The full price is paid at checkout; shipping, duties and taxes are shown before you pay.

Is it road legal?

AD-01 is intended for motorsport and closed-course use and is not currently type-approved for road use.

How is it installed?

A specialist workshop should review fitting and ECU calibration for your chosen configuration. UAE fitting is available through APEXLAB by appointment.

What happens after I order?

We review your car and configuration, then confirm the specification, lead time and delivery details with you before production starts.

Can I buy components separately?

Yes. Headers and the cat-back are available individually, with catalysts and tips as options. We review compatibility with your existing setup before production.
