Direct-Fit Rear Catalytic Converter for 1989-1994 Ford Ranger (VN58)

What it Does: The rear catalytic converter replaces fouled or flow-restricted factory emissions units on the 1989-1994 Ranger to restore optimal exhaust gas velocity, resolve tailpipe emissions failures, and eliminate excessive backpressure.

The Stock Ford Ranger Substrate Breakdown and Flow Choke

Decades of continuous heat cycles, unburnt hydrocarbons, and rich fuel-trim conditions degrade the factory ceramic substrate on aging Cologne V6 exhaust assemblies. Internal honeycomb structures fracture, melt, or suffer heavy carbon fouling, converting the original rear converter into a severe exhaust restriction. This restriction spikes exhaust gas temperatures (EGTs), suffocates top-end engine breathing, and causes sluggish throttle response during load demands or hauling.

The Engineering Solution

Built to factory exhaust geometry, this direct-fit unit features a heavy-gauge stainless steel outer shell engineered for high corrosion resistance and thermal containment. Internally, a dense, high-flow ceramic monolith coated with active precious metal washcoats ensures rapid light-off and reliable chemical conversion of HC, CO, and NOx without restricting scavenging flow. Precision OE-matched inlet and outlet connection flanges mount seamlessly to existing factory exhaust hardware, bypassing the need for cutting, torching, or custom pipe bending.
