Valvetronic Designs Porsche 718 Cayman Gt4 4.0L, Catback, Grade 5 Titanium, Titanium 4.0" Outlet Tips POR.718.GT4.VSES.TI

The Porsche 718 GT4 and Boxster Spyder are outstanding driver’s cars, but their factory exhaust note lacks the character and intensity enthusiasts expect. Valvetronic Designs changes that. Drawing from our development of the 992 GT3 RS and GT4 RS platforms, this valved exhaust system injects the high-pitch exotic tone Porsche purists crave—transforming the flat stock sound into something truly spine-tingling.

This system blends lightweight titanium craftsmanship, race-inspired headers, and OEM-level integration to deliver a raw, emotional sound without compromising drivability.
