Yamaha GP1800R Exhaust Install 

Sounds better in the water under a load. I think I’ll do another vid while on the water so you can hear it 😎

People don’t want to drill holes in the exhaust so that when they want to sell it they can bc people who are looking for a jetski want stock

Oh yea I got one to and she fucking whines and the bov helps with protecting it I’ve had a GP for 3 years now and I can tell you I’ve went through 3 superchargers😭

Add a blow off valve and that unloads the super charger clutch’s as soon as you back off,

The battery part number is 490-2525

@@QuadStar721 Thank you!

Not sure. You will need access to the back of the ski in order to bolt on the coupler tho. Just depends on how much room you have behind it

@@QuadStar721 ok thanks. I just wanted a simple riva free flow exhaust. Idk if that’s what u did also

The exhaust came with a flat rubber gasket that goes between the flange an the hull I did use loctite on the bolts though. No leaks

@@QuadStar721 I used the rubber gasket but also put a bead of silicon & used loctite as well... Can't wait to get it out on the water to hear it!!

Not much you can do other than a Riva Racing water box or TDR waterbox. It helps a little and sounds mean🔥check the link below ru-vid.com/video/%D0%B2%D0%B8%D0%B4%D0%B5%D0%BE-ULucENFg-LY.html

@@QuadStar721 Thanks

Blue Loctite was used to keep the bolts from backing out and will help seal it from water leakage

Hey Jimmy. At the beginning it was just a short run for sound. Motor wasn’t even warm to the touch when I started to work on it😎

Hey mate what benefits do U get bye putting on exurst system?

@@roscoadventures2194 Better throttle response and sounds awesome on the water. Get compliments all the time

Cheers mate I have same ski it's a machine👍

Yeah.. the stock waterbox is so restrictive. I just got the Riva waterbox, can’t wait to install it 😎
