Jaguar S-Type Catalytic Converter - Magnaflow - Direct Fit, CARB Compliant - `03-`05. A California-grade, direct-fit replacement designed specifically for 2003–2005 Jaguar S-Type applications to restore emissions compliance and maintain engine management without cutting or welding.

This MagnaFlow converter reproduces OE spun-body geometry using advanced 3D scanning in R&D to ensure accurate fit and function. Constructed with corrosion-resistant stainless steel and mandrel-bent tubing, it provides controlled exhaust flow to help maintain factory performance and fuel economy. The unit interchanges with OE numbers XR858404 and XR858405 and ships with the necessary gaskets and hardware to simplify installation. Its laser fusion weld and compact, low-mass design reduce leak points and support efficient thermal transfer.
