These pipes hit super nice IMO, I ran on pump and race gas 900 setups with good success except in sand. As with any wet pipe the filters clog easily and the pipe over heats quick. In normal non sandy areas they are awesome.
I am back on a PFP now, both make great power just in different places, I will never understand why someone would run a PFP wet, just get a lay down wet pipe, inner diameter is larger and they function better, run the PFP dry and know where your power is. Both options are awesome when properly tuned. Even the TNT is a good option, just keep an eye on water flow on any wet pipe. Dry pipes will simply overheat the water box if clogged, wet pipes will melt EVERYTHING when clogged.
