Product Description

4 to 1 DTM Style Race Header for E30 M3 S14

This header has 2 inch primaries of very long length. We went to great lengths to keep the primary length as equal as possible. Our jigs were made with the engine in the car completely, these are not copies of any other headers on the market. Software analysis was done in an effort to increase torque on a 2.7 liter S14 with mild cams, but this design will also work well race S14 2.5 liters and up with large cams.

These headers utilize a true merge collector. 100% TIG welded. Primaries are 2" and go to a 2.5" collector outlet which we tapered out to a 3". We have a couple different configurations available as well and these can always be modified if you need slightly changes to get them to work. Price doesn't include an O2 sensor bung but does include springs to hold the primaries to the collector. O2 sensor bungs can be added at additional cost. Ceramic coating can be applied at additional cost before these are shipped.
