Milltek's Cat-Back for the Chevrolet Corvette C8 Stingray 6.2 V8 and E-Ray is a 3-inch (76.2mm) T304L stainless steel system with quad tips that deepens the V8 note while retaining the car's OEM exhaust valve function, at direct OEM fitment. It is built for C8 owners who want a stronger, richer tone without losing the factory valve control, and bolts straight to the OEM mounting points. What is the Milltek cat-back for the C8 Stingray? It is a full cat-back replacement in hand-finished T304L stainless, mandrel-bent in 3-inch (76.2mm) pipe, finished with quad tips. It retains the OEM valve function, so the car's own quiet and loud modes still work, now with a deeper Milltek voice behind them. Who is it for? It suits the C8 Stingray or E-Ray owner who wants a noticeable tone upgrade with full OEM valve behaviour intact, rather than a fixed-volume system. What does it include and what are the specs? The system ships as a complete cat-back with quad Burnt/Blue titanium tips, OEM-compatible hangers and the fixings for a bolt-on fit.

This is a cat-back, so it does not change the catalysts. It fits non-OPF/GPF models, so confirm your car's emissions equipment before ordering. On a cat-back alone, expect a tone and character upgrade rather than a headline power figure. Every system is built in hand-finished T304L stainless. (Source: Milltek Sport, About Us.)
