inside of a waterbox

[Jetpilot106]

My 440 runs good without it, just really loud.

my ski runs fine without the baffle in. but i had no choice i could not find a used one and was not gonna buy a new one. it got a little louder but its not too loud.

i have a sn with the stock box. besides being lighter, is there any advantage to running a rn box in mine?

It won't blow up when the ski backfires and put your ski out of commission for a week or two.

eric,seems like alot of the big motor setups are running baffless wb some with front exh as well.isnt the stinger size reducer making the largest diff for back pressure for the sound wave. I hate them myself,I removed the tdr in my superjet,Wilkey was running a xmetal with front and rear exh,everyone bitched about it,he finally grew to hate it also and removed it.We are slowly weeding out the tdr wb in the b1s in the group,you can never hear what anyone riding one is saying in the slow wakes. they suck and provide no extra power
