I don't know how soon I'll get it put on, because I'm probably going to wait until the weather breaks so I can take it somewhere to get it done, or at least a day or so after a good rain to wash the salt off the roads. The inlet is 2.5" so I'm thinkin on getting a new rear section made, especially so I still have the stock exhaust to put back on if I want. How much do you think it would cost for installation?
