THE DUNDON BUILD

WHAT IS A DUNDON BUILD?

A Dundon Build can start with one system. It is the right Dundon product, or combination of products, selected for your chassis, your driving and your goals.

  1. Tell us your car and how you drive it

    Chassis, model year, the parts already on it, and whether it lives on the street, the track or both.

  2. We recommend the stage

    One system or a full package, in the order that changes your car the most, not the longest parts list.

  3. We confirm fitment before you order

    We check the parts list against your chassis and model year with you before anything is ordered.

QUESTIONS

BEFORE YOU BUILD

How do I know which parts fit my Porsche?

Pick your car under Shop by car to see the parts and packages made for it, or send us your car and goals. We confirm fitment before anything is ordered.

Which stage do I need?

It depends on how you use the car. Packages are staged so you can start with what you need and step up later. Tell us about your car and we'll recommend a stage.

What is a Dundon Build?

A Dundon Build can start with one system. It is the right Dundon product, or combination of products, selected for your chassis, your driving and your goals.

What is the difference between EU and non-EU exhausts?

Non-EU header packages replace the factory particulate filter (OPF). EU/RoW versions keep it. Choose the version for where your car is registered and driven, and ask us if you are not sure.

Who installs Dundon parts?

Any qualified Porsche specialist. Our Preferred Installers are shops we trust to fit Dundon parts, and step-by-step guides are on the Instructions page.

Do you ship internationally?

Yes. Orders ship to the US and to international markets, priced in USD. Duties and import taxes are the buyer's responsibility. Ground shipping is free on eligible orders over $2,000; aerodynamics, brakes and wheels are excluded.

What warranty do Dundon parts have?

Dundon exhaust products are warrantied against defects in materials and workmanship for as long as the original owner uses them. Parts Dundon sells but does not make carry their manufacturer's warranty. Full terms are on the Policies page.

I run a shop. Can I become a Dundon dealer?

Yes. Shops that sell or install Dundon parts can apply for a dealer account. Approved dealers sign in to the Dealer Hub for dealer program pricing.
