Fit Confidence

JP Group is a long-established European supplier of OE-style replacement parts for air-cooled Porsche models, and Washburn's Metal stocks this line specifically because of its consistent fit against factory tolerances. As with any exhaust, brake, heating, or chassis component on a 40-60 year old car, inspect surrounding hardware, gaskets, and fasteners at install time — a part this age-appropriate is only as good as the mounting points it bolts to.
