depends on the waterbox used.
the old xmetal box was obnoxious.tdr was bad too.
the stock or factory pipe box are not bad at all and you can inject more water at the Y to make it almost as quiet as stock.

I have front/side on my current ski with a modded stock waterbox, its not any louder than an aftermarket waterbox. I really enjoy mine, never had a single complaint about noise with it, if your interested I can text you a couple videos of my ski running.

I recently bought a ski that had front and rear.

On the first ride I realized it was beyond obnoxious. Shortly after that, I wrapped a bottle cap in duct tape and plugged the front hole. Thats how desperate I was to not have to hear it. It will be fully blocked off/eliminated this winter.

If you are doing old school freestyle, Tail stalls, spins, 50/50's, Monkey Jumps, Then you need the front side exhaust. If you are not, there is Zero Benefit. What it does, say you are doing a monkey jump, when the tail hits the water, the pressure forces the exhaust out the front. "Path of least resistance", This lets the motor keep going and not get choked, Also, it keeps exhaust gasses from going into the intake track, this is your largest benefit.

Understandable...but isn't there always more restriction on the rear than the front? Thats what it seemed like with mine, so the majority of the exhaust always came out the front.

yes but this is why the front is smaller diameter and injecting h2o at the Y helps considerably.you can also restrict the front more as needed.

Yes it's for old school freestyle but what I do not like most is breathe too much smoke:confused:
si tu n'aimes pas la fumee et l'odeure des hydrocarbures je pense que le jetski n'est peut etre pas ton sport,heureusement pour toi de ne pas avoir fait tes dents sur un 440/550!
