Chevrolet Corvette Z06 C8 5.5 Valved Exhaust System (2023+)

The Chevrolet Corvette Z06 C8 5.5 exhaust in detail.

The C8-generation Z06 is not content with a more powerful V8: it receives the LT6, a 5.5-litre naturally aspirated engine that revs like a racing engine. 679 hp and 624 Nm, with no turbo or supercharger, for a Corvette designed for the track as much as the road. The page covers the C8 Z06 from 2023; the Stingray Z51 with the 6.2 engine has its own.

With an engine like this, the exhaust decides almost everything you hear, and the factory one holds some of it back. With the valves open, the Rog valved cat-back lets the naturally aspirated V8 stretch all the way to the top of the rev counter, without any unnecessary filter. With the valves closed, the Z06 becomes presentable again in town and on the motorway, as close as possible to its stock sound.

The system, built to your VIN and checked before production, fits with clamps and gaskets, without welding, in about two hours. The factory valve control is retained if the car has one; otherwise, the Rog remote and its unit in the boot take over. This page includes no front part: the LT6 has manifolds of its own, and the system connects behind the factory catalytic converters, without an ECU remap. For the Z06’s round tailpipes, two materials: tough 304 stainless steel, or titanium, around 40% lighter for the same design, whose brushed, gold or purple finishes suit a track car.
