FMF powercore 4 question

I have a 06 wr450f. I have the chance to pick up a brand new powercore 4 slip on for $100. The problem is that it is for a 04 yz450 , does anyone know if it will work on my 06wr. I'm new to riding and this is my first mod. Thought it was a good deal if it will work. Please let me know.
