Exhaust super sound Type Riva – Porsche 911 (993)

Our latest version for the 993: its sound decouples the sound level from the engine rpm. Compatible with fitting a sport catalytic converter. Three Riva characteristics:

• A bark at start-up
• A very soft cruising sound
• Dynamic rev variations

Fitting

• Strictly original interfaces (inlets, outlets, dimensions): direct replacement of the original part
• Mount directly after the catalytic converters
• Average fitting time: 2 hours including removal. No need to remove the rear bumper
• A lift is essential: the mufflers come out from underneath
• Tighten all nuts progressively
• If your original mufflers are Gillet-style, get 2 olive gaskets and 2 Bischoff muffler clamps from Porsche
• Fitting kit included: stainless bolts, stainless lock nuts, high-temperature copper grease
