Header, intake and exhaust (cat back) do not need to be changed at once, your car still runs by just changing the muffler. however, have those 3 all changed, will have the best performance, according to the Dyno. If you are just driving street, no need to replace all of them. A better air filter like K&N stock replacement, or if you want a little racing sounded, get a nice piece of muffler or the cat back (Tanabe Medalion Touring or Apexi World Sport II I suggest, nice and quite), that will do for Daily Driving already
I'm fine with the first 2... they're pretty quiet... but then...
exhausts, intake, header... seems like Kut 1 But Hor... so once change = change all three? $$$...
