I have mine ordered, should be a few weeks until it's ready. I got mine with the ceramic coating, and with everyting it came to about 440 shipped. You may want to talk to selector about the performance, he is the only one I know of who has the Thunder Alley mounted. They say with the longer header it gives it more bottom end. If you are going without the ceramic coating it is 350, if you want the coating add 70, and 18 bucks for shipping. Im sure selector will explain more about this pipe if he is aware of this topic.
