1004/09/2013WRXExcellent bang for the buck. Perfect fitment. Made great power gains over stock double catted pipe. Thermal blanket also makes a BIG difference. Keeps heat where it belongs, in the pipe.
503/09/2013STiLooks great but this does not fit JDM Sti ... The oil pan is different than USDM ...
1009/30/2012LegacyDownpipe was made very well. Easy install and great performance gain over stock pipe. Would reccomend to any buddy wanting a quick and easy performance gain.
910/06/2006WRXThis downpipe is a good buy. It is easy to install and sounds great. i definatly could feel the power differance over the stock downpipe.
911/28/2005Legacyvery well manufactured, heavy duty but not excessively heavy, removed the cats and one flange in the ex system,small increase in ex noise, good seal and clearance don't forget to get a new turbo shield
