Spark Arrestor End Cap

I have a 2014 KX 450F. I need to get a pro billet spark arrestor end cap to be able to ride certain places. Pro billet does not have a product for 2014 yet. I was told that the KX did have any changes done at all between '13 and '14. Does anyone know if the '13 will fit and work on the '14. Pro billet will not confirm or deny this for me, they said to call back in 3 to 4 weeks. I'd like to get riding sooner than that. In theory the endcaps would be interchangable correct? The kawasaki dealer where I purchased wont give me an answer until they also hear from pro billet.

If no changes were made, I see no reason as to why it won't work from a 2013....

The Kawasaki part number for the stock muffler are the same for 2013 & 2014. So it should work.

I would swap dealers if they didn't have enough sense to check if the 13 and 14 stock mufflers were the same part number.
