The turbo whine and blowoff sounds amazing with the CAI, but the air sucking sound at idle is obnoxiously loud haha. Plus the only CAI that supposedly does not trigger a CEL is the Injen (MAF sensor is sensitive on these cars), but it's $300+ and the mod list is too long to spend that just for an intake. The intake tube and drop-in filter I bought will make everything louder, and some people even cut the airbox a little for more whoosh haha.
I cannot wait to get more sound out of this car, I hate how quiet it is. The intake, catless downpipe, and Borla exhaust should make things much better once it's all on and tuned.
