Description

The K-Tuned Ram Header is a high-performance exhaust manifold designed for K20 and K24 engine swaps in DA, EG, EK, and DC2 chassis. This long-tube header features a 4-2-1 stepped design and is engineered to enhance ground clearance while maximizing mid-range and high-end power gains.

Constructed from 304 stainless steel, the header utilizes three true merge collectors and equal-length tubing to optimize exhaust flow. The system transitions from 44mm to 47mm to 50mm primaries, ending in a 2.5-inch exit.
