Sport catalytic converter (200 cells) – Porsche 911 (993 Turbo)

This version is fitted with 200-cell HJS sport metallic catalytic converters, instead of the original 400-cell units: they replace the original converters with better flow and more sound, with an expected gain of 10 hp on a stock 993 Turbo.

Fitting

• Strictly original interfaces (inlets, outlets, dimensions): direct replacement, no modification
• Mount under the car, between the turbos and the mufflers in the wings
• Before removal, unplug the Lambda sensors at the connectors and remove them once the converters are off. Reusing them is not straightforward: be ready to replace them
• Take the time to adjust the converters and the heating connections welded to them before tightening, progressively
• Average fitting time: 4 hours including removal
• A lift is essential
• Fitting kit included: gaskets, stainless bolts, stainless lock nuts, high-temperature copper grease
