93-98 Grand Cherokee 4.0/5.2L Cat Converter

The 93-98 Grand Cherokee 4.0/5.2L Cat Converter from MAGNAFLOW PERF EXHAUST is engineered for owners seeking improved exhaust flow and emissions compliance on first-generation WJ Grand Cherokees. Whether you're building a modified 4.0L inline-six or rare 5.2L V8 setup, this catalytic converter balances performance gains with OEM-level regulatory adherence. Factory converters on these models are known for restrictive internals and carbon buildup; this MagnaFlow unit directly addresses those limitations with a high-flow substrate design that reduces backpressure while maintaining catalyst efficiency.

MagnaFlow's construction uses a stainless steel shell and ceramic monolith substrate that withstands thermal cycling and vibration common in off-road and highway use. The converter's 25.25-inch length and 8.5 x 4.75-inch envelope fit the factory exhaust routing on 93-98 Grand Cherokees without additional fabrication or clearance modifications. High-flow converters reduce exhaust gas temperature (EGT) spikes that accelerate wear on downstream oxygen sensors, while the optimized catalyst loading ensures your vehicle passes emissions testing in regulated states. At 5.85 pounds, the assembly integrates seamlessly into existing exhaust systems with minimal installation labor.

This converter is ideal for stock and lightly modified Grand Cherokee owners, weekend off-roaders, and builders transitioning from emissions-deleted setups back to street-legal compliance. The 4.0L engine particularly benefits from reduced backpressure, which improves low-end torque delivery and fuel efficiency on highway driving. Installation requires basic hand tools and jack support; the unit bolts directly to factory upstream and downstream connections, making it compatible with OEM piping. Verification against your specific model year and engine code before purchase ensures proper fit, though this converter covers the full 1993-1998 production range for both engine displacements.
