I just ordered one for my 2014 in mid January, was shipped and made it to the USA in 3 days. For some reason USPS sat on it for a week then I got it. Much thicker than the P3 and extends up to the end cone on the expansion chamber, you know the part that hits the ground if you go over sideways, the P3 ends before this point. Fit is great, cost is the same and the customer service at ProPower is excellent. Wasn't sure what was happening with the shipping and sent them an email. Got a response within an hour with an updated response in 8 hrs, then a follow up to make sure it worked out. Also came with a T shirt and a coolie cup for free swag; truly a company you want to support especially since they have the better product. Cost was $170 or so to my door.
Thanks ProPower!
