I will bump and say these pipes are amazing in non sandy conditions, I run one on my ninja 900 motor and love it, solid range of power. The PFP is great but to me this pipe gives as much power but more level across the throttle.
throw in a waterbox and i will take it LOL. RRP or Bun Waterbox will suit me fine LOL

What happens in sandy conditions? Cooling jacket flow not up to par for purging sand? Or injection point clogs?

I havent run this pipe in sand, I have run TNT and RRP wet pipes and they clog BAD.
PFP has exit pisser run from bottom of water jacket so gravity is huge in this factor. I have never clogged a PFP but never not clogged a wet pipe in sand.
I keep my PFP setup for surf trips now, Just swap chamber and waterbox.
This chamber IMO is worth the swapping though

Funny , the last PFP I bought the jacket EXIT was on top, not on the bottom like my original….don’t mean to “muddy” the sale thread, bump for a good seller!

ok, if dude is still making them i will be getting 2. I cant even pretend to understand how it self cleans even after reading his description.

But I ride in fear with this Bun pipe (love the power but hate the clog risk and the fact that if you get towed your motor will get water in it.

I tried a 1/4" flow control to avoid the flow to spray bar while towing but it got the pipe too hot even backed all the way out.

i installed a 1/4" shut off , but you have to open hood in open water to shut it off before towing.

Any brilliant ideas are welcome on that fix as well, all problems a dry pipe doesnt have, but i like the power and that it is less than half the weight of a water filled PFP pipe.


this is officially the BUN fix thread, thanks aquaholic
