upgraded turbo question
my car is a 2004 wrx stage 2 with a 38mm external wastegate.
recently, i took of my magnaflow 3" catback and replaced it with the stock wrx catback, which on the 04 is a dual tip. i still have the perrin 3" dp on there.
the car runs great, and is silent until the gate opens, then its a different story
after i swapped the exhausts, i really couldnt notice any loss of power...the car pulls strong and hard, and i seem to have gained a little down low.
now my question is, if i go upgraded turbo soon, along the lines of an 18g, would i need the 3" catback, or could i keep my stock catback? how much power would i be losing if any?
i know i could always get a borla hush, which is the best of both worlds, but id rather put the money to a turbo rather then a third exhaust
