I got it from Exhaust Now for $879. Here's their link:
Corsa Exhaust System #14578. There was one other place locate in CA as I recall for $876, but I had read that Exhaust Now ships out of Ga and it will arrive in 3 business days from the day you order to NC, which it did. If you live in Charlotte, it will arrive in 2 business days because that's the route they take to deliver to our state. Take care. You will truly love this exhaust.
