SPDZ1 High-Flow Tri-Y Header

Part Number: (SZY-053-Cattless)

Designed specifically for enthusiasts looking to maximize the performance of Honda's dependable K24 engine, the SPDZ1 High-Flow Header replaces the restrictive factory exhaust manifold with a precision-engineered Tri-Y design that improves exhaust scavenging, increases airflow, and delivers noticeable gains throughout the RPM range.

Manufactured from premium 304 stainless steel with CNC-machined flanges and TIG-welded construction, this header is built to withstand years of daily driving and spirited performance use.

The included high-flow connection pipe offers significantly improved exhaust flow while helping reduce exhaust odor compared to traditional race headers. The stepped primary tubing and true 2.5-inch collector are engineered to maximize horsepower and torque without sacrificing drivability. The competitor's published specifications include stepped tubing from 1 7/8" to 2.0" to a 2.5" collector, Tri-Y collectors, 304 stainless steel, CNC flanges, and a high-flow catted test pipe.
