GT Valved X-Pipe
Fabspeed's valved exhaust design: valves open for full flow and an aggressive note, closed for a tone smoother than stock. A crossover pipe joining the two exhaust banks into an X shape, smoothing flow for a fuller, balanced tone. for the McLaren GT and GTS (2020+), replacing the factory muffler's quiet default tone with a smoother, higher-pitched exotic note from the twin-turbo V8. Built from CNC Bent over an internal mandrel so the tube keeps a constant diameter through the bend, unlike crush-bending. T304L stainless steel around Fabspeed's cast X-pipe, fitted with Helical UK exhaust valves, and scanned from the OEM muffler for a precise fit. Retains the factory valved exhaust functionality and drive modes, and saves 3.2 kg over the factory system.
