More or less the same sites everyone is looking at: subispeed , subimods, grimmspeed, every "ralli / rally" store.@Gadabout , couldn't have said it better myself. Where are you searching typically anyhow ?
Perhaps if you searched the forum you would have found this thread, which answers your question: http://www.impreza5.com/forum/154-intake-exhaust/1890-after-market.htmlNo word on intakes or if any of the older intakes fit the new Subaru?
Could you perhaps post a video so we could get a sound clip of how the set-up sounds together?I have a '17 Impreza Sport and I have installed this TSUDO 304 SS exhaust:
It required me having to cut the exhaust a little after the resonator, remove several inches, then rejoining the two.
For the air intake I have SSD Cold Air intake kit for the 2012-2016 Impreza and KN filter:
The only adjustment I had to make was get a larger air intake coupler for the airbox fitting.
