The stock Subaru STI Y-pipe is useful for a number of reasons. You can use it to adapt an STI intercooler to your non-STI WRX (pre-2008), or to fit a number of aftermarket intercoolers. Or you can just replace the stock STI one you managed to lose.
Fits all 2004+ STI cars, including 2008-2014 and 2015+.
