The Knuckle Performance T25 FLOW Turbo Adapter is the premium evolution of our proven KKK to T3 adapter. Designed for enthusiasts who demand improved exhaust flow and turbo response while retaining the factory Mercedes-Benz exhaust manifold.

Unlike traditional compact adapters, the T25 FLOW features a full-size T25 Single Entry flange and an optimized internal flow path, reducing exhaust restriction and improving turbocharger efficiency. It is the ideal solution for builders looking for maximum performance without upgrading to a full tubular exhaust manifold.
