I just got the Injen upper I/C pipe, installed it in less than 15 min. I am very happy with the results, It definatly kicks harder and spools up qwiker than before. Especially because i am tuned peaking boost @ 19psi the stock soft pipe expands a lot when your WOT which is fighting against the little turbo. (Like our turbo needs something like that) +1 for upper I/C pipes.
