HONDA R18 UNEQUAL LENGTH HEADER

This header is for the honda civic with the R18 motor. The primaries are 1.625 and collect into 2.25. The bends are 304 stainless and are mandrel bent. It has both upstream and downstream O2 sensor ports and the EGR as well.this will help to bring out the rumble similar to a subaru, however to get the most out of it you will need to separate the two sides in the head. because it collects inside the head, a UEL header can only do so much. build times vary, please allow 12-16 weeks for completion.

(my products are custom built to order. i have a full time day job so lead times vary.
please be patient and if you have any questions dont hesitate to ask. if i dont reply right away its because im either at work or in my shop building headers.)
