PPM Manifolds: One-Piece Power, Zero Leaks Say goodbye to leaky expansion joints. PPM manifolds are built as a single, solid piece—eliminating the weak points found in traditional three-piece designs. With a wider airflow channel, these manifolds move more air through your engine, helping lower EGTs and boost overall performance. In real-world tests, we've seen up to a 100°F drop in exhaust temps compared to standard manifolds.
Perfect for CAT, Cummins, and Detroit engines pushing harder than stock.
