The kit I ordered for my predator 212cc came with a header flange with incorrect mount hole spacing and a paper gasket to match. The kit wasn't to include an exhaust gasket. I reamed out the holes to make the header fit and used my old gasket. I then sent an email to notify the company. Greg responded apologetically and said he'd send the correct gasket "as a spare".
The next morning, Tim emails me telling me that they checked their remaining kit manifolds and all fit doubting my story! What? I wasn't asking for a refund, just letting them know of my disappointment! Tim impressed upon me what a jerk he is and that he should take some classes in customer service.
The following day we ordered 2 stage 2 kits and flywheels from a competitor. There will be another ordered later this month. If you order from GoPowerSports, better hope you don't have a problem!
