if you stay n/a....get the greddy mx. best performance for n/a.
if you plan to go n/a-t, might as well get the n1 or any other catback for a turbo car. the low end loss is marginal and you do gain some noticeable high end.
I bought the n1 when I first got my n/a, looked awesome, sounded great. Now that I'm turbo, its even better
