Get a GMMG chambered exhaust for nearly half the price. Sounds better anyway.
I'd have sent it back once I figured out it wasn't going to fit. I might have included pictures to help prove my point, but for $1300, it better fit. Once you start cutting on the pipes, you own it, sorry to say. I doubt if Borla will compensate you anything on that.
Let us know how it turns out.
