1 tailpipe Exhaust system – Sport sound – Porsche 911 (964)

A complete line that replaces the entire original line, with a +20 hp gain: spaghetti manifolds (without heating) and a rear centre muffler. The Lambda sensor port is fixed on the left manifold. Twin-outlet versions are louder than single ones: this is therefore the quietest of the 4 versions – the one we recommend for track use.

Fitting

• Average fitting time: 4 hours including removal (quicker if the old exhaust is in good condition)
• A lift is essential
• Respect the manufacturer’s torque, tightening all nuts progressively: under-tightened leaks, over-tightened leaks too
• Fitting kit included: gaskets, stainless bolts, stainless lock nuts, high-temperature copper grease and the 2 Scart straps
