Sorry fellas if this is a repost (I'm pretty sure it's been discussed before ), but after a quick search I couldn't find the answer.
Is there any difference between a '06 factory STI exhaust and that of a WRX? My wife has a bone-stock '06 WRX and a friend of ours is selling an STI exhuast, so naturally she is thinking about maybe doing an upgrade.
Any cons/pros??? Thanx in advance.
