I have a relatively new (4k miles) SPT CBE for a 2011 WRX Sedan its the NEW dual tip.
Im located in NJ, 08037. Willing to meet up with someone for pickup...
It does NOT void the Subaru warranty and I will also INSTALL it for FREE if you pick it up at my house and pay my asking price...
MY PRICE: $700 OBO
I paid: $1100 after tax and everything
Here is a video comparison of the stock vs the spt sound.
