The GWR POWER MAX header is the original unit designed for the street driven 2.0. Great set up for increased output on a stock or near stock NC. Solves the issue with the factory header "squish" where the collector meets the primary tubes. One of the best things you can do for your 2.0!
Requires the use of a GWR midpipe, (or a second O2 bung welded into your factory midpipe), and two O2 extension cables.
