Thanks, I'm getting ready to do this job myself. Now I know what I'm getting into.

[@gotstajump]

All done with one hand!

[@amg5721]

you should have put the plug in first after you drilled the new hole , easy to get your hand in there to do it

[@zchhrrs4590]

Sounds like it gets rid of all of the drone by sending it out the rear like that

[@johnabitino8786]

Hello Do you have the link to the drill bid by any chance

[@Daniel-zv5rm]

I have the worx freeflow and riva waterbox on my 22 gp svho. About to buy the rear exit for it. Is it a lot louder at idle in the water and does it sound much different in general?

[@QuadStar721]

It is louder and throaty but not by a ridiculous amount. I get compliments all the time.

[@gerardotorres9963]

Very very good job I just did it. Oh my 21 gp1800r svho and let me tell you something. It was really hard for me to align the screw on the back you use to drill bit good idea I got to do the same thing to my 21 FX cruiser SVHO you make it look easy. What is the real pain in the ass?

[@QuadStar721]

Thank you! Exhaust coupler was the hardest part to install. Had to make sure it has perfect alignment or it could leak or worse not align with the exhaust tube. Well worth the effort tho😎

[@gerardotorres9963]

@@QuadStar721 yes, I have the same problem I it took me a couple hours

[@DMDOGG]

Nice man.. what BOV is that?

[@QuadStar721]

It’s a Turbosmart BOV with Fizzle tubing upgrade.

[@viewoptic]

Do you get any drone sound with the rear exit compared to the free flow?

[@QuadStar721]

In my opinion less drone do to rear exit and sounds way better too😎

[@viewoptic]

@@QuadStar721 Way less drone?

[@chrisskywalker8811]

Will this work on a rave runner ex deluxe?

[@seiftalaat1586]

What is making that tsss sound is it the fizzle intercooler?

[@QuadStar721]

The release of pressurized air from the Turbosmart blow off valve I installed.

[@michaelbarkley6213]

It’s reeeeeeva

[@QuadStar721]

Lol. Got it

[@1010Nato1010]

Sounds like my chainsaw.🤣

[@LizardHunter777]

I want whatever Chainsaw you have lmao

[@user-vi3wn9ho3h]

What about the cleat you removed?

[@DMDOGG]

Lol

[@kckrol85]

Did you have a transom plate leak that you resealed?

[@QuadStar721]

So there is a little water after each ride in the back of the ski. I do believe it could be that plate

[@kckrol85]

@@QuadStar721 It is. I noticed you had some sealant on the inside that didn't look like it was from factory and then I realized you did a cooling upgrade.

[@HondaFn1]

Ain't no way i would do that just for sound

[@dbonics420]

If you at least also swap the waterbox. You'll get a direct hp increase and not just sound. But with supercharged motors increased exhaust/intake will only benefit the ski

[@JimHawkins-iv3cp]

Have u done an Intercooler yet

[@QuadStar721]

Yeah I do have plans for a Fizzle intercooler install soon

[@turbostang880]

What was the HP or MPH gain from this?

[@QuadStar721]

Well the butt dyno tells me better acceleration. Not sure if there was a HP gain tho. MPH didn’t change but sounds awesome 😁
