NOS VW Performance Header & Muffler System — 4-into-1 Extractor

This is a New Old Stock (NOS) Volkswagen Performance Header and Muffler System designed for the classic air-cooled flat-four engine. This all-in-one "extractor" style exhaust is a period-correct upgrade for owners looking to improve engine breathing and achieve a deeper, throatier exhaust note. Tubing measures 1-1/4" throughout the system except at the ports, where it steps up to 1-3/8" diameter.
