Give your right-hand-drive Mustang the Kooks upgrade it needs

Choose a header package made for your right-hand-drive 2015-2019 Mustang GT. These Kooks kits pair stainless long tube headers with catted connection pipes and OEM adapters, offering 1-3/4" Performance, 1-7/8" Performance or 1-7/8" GREEN combinations.

SKUs: 1155H220, 1155H420, 1155H430

Made for the right-hand-drive installation

RHD is part of the application for all three kits, rather than a detail to assume from a general Mustang listing. Each package uses 3" collectors and includes the connections and adapters to the OEM rear exhaust.

Choose for the engine you are building

The two Performance-catted kits suit naturally aspirated 5.0-litre engines. The GREEN-catted 1-7/8" package supports forced induction. Compare the actual combinations below and choose around the engine and rear exhaust you plan to use.
