Our K24 86 swap header maximizes the space available in the engine bay and provides the best all-around header for both stock and modified engines. And for 2024, we've updated the supplied midpipe to include a built in flex! This flex, combined with the supplied hanger, eliminates excessive strain on the header and O2 sensor.

It’s built from 304 stainless steel and features a 4-2-1 runner design, with proper 1-4 and 2-3 cylinder pairing. Thanks to the width of the engine bay, runner lengths and diameters have been optimized for both peak and midrange horsepower and torque. Due to these dimensions, this is the best performing header out of our entire lineup. 

The header terminates with a three-bolt flange, which transitions to a small 3” midpipe section that fits around the lowered transmission. It also includes a port for a wideband and then ends with a two-bolt 3” universal exhaust flange in the exact location as the stock midpipe. Pair up our midpipe with any aftermarket 3” 86 exhaust for a straightforward exhaust solution.

All necessary hardware is included.
