Thanks for the info Chris, I would not of known to check that. If I have any issues I will definately order new ones from Jetsareus.com Can you give me a rough estimate of jet size for pod filters and aftermarket exhaust. I will need a set for both Florida and Colorado. The elevation change will be 10,000 ft. The town I live in is 7,300 above sea level. I was thinking 137.5 for Florida , which is two sizes over stock. Does that sound right?
