Guys, sorry for what seems like a noobish question, but I can't find info on this exact set of questions anywhere. Would a 2011 STI exhaust bolt right up to the same model year WRX? And if so, would it sound any different? I have been searching here and NASIOC, but the threads I'm finding revolve more around aftermarket exhausts for one model fitting another. Just wondering if I could get a slightly deeper rumble without spending $1000 for the factory SPT.
