Litchfield Porsche 718 GT4 exhaust testing

Early this year we visited Castle Combe circuit to test versions of our new Porsche 718 GT4 exhaust systems. We invited car enthusiast and TV presenter Paul Cowland along to give his thoughts. Our new exhaust fits after the Porsche sensors and OPF/GPF filters to provide both a performance improvement (+20Bhp) and weight reduction (-6kg) but more importantly gives the GT4 back the exhaust note it deserves. We have been careful to develop a system that strikes the right balance between releasing the 4.0 engines sporty, charismatic sound without being obnoxious and overly loud for track use and other road users. Watch as Paul tests the GT4 before and after our exhaust system is installed For more information on our GT4 exhaust upgrade visit our website
