    Check out this dual exhaust setup on a Sea Doo GTR

    One of my customers by the name of Randy fabricated this setup based off of Riva rear exhaust kits he purchased from the GreenHulk Store and I thought it was too good not to share with you guys.

    Here's what Randy had to say about the job:
    Got the Riva GTR exhaust kit today, got it installed with my custom dual exit exhaust on my 2012 GTR-215. You asked me to send you some pics of the install, so here is a few pics. The first pic is were i cut it open and installed the dual exit pipe on the left side .I saddled it in to the factory out let pipe to mirror it . so they would flow together. then tig welded every thing back up. The second pic is the out let pipe for the exit left side , there is plenty of clearance on the back side of the water box for the exit pipe. I used the factory rubber pipe and cut it at the right angles to make the proper bends. and used a piece of stainless steel pipe to extend it to the rear.(all i had) lol... . I was a pipe fitter & welder for 30 years and just wanted to see if i could do it. And also i could (not) use the templet take came with the Riva kit to layout the right side exit, because it would not match the custom layout on the left side . There was only a very small window were to place the exit pipe on the left side , so i had to match them together . But didnt haft to modify the Riva kit, just had to extend the rear exit rubber connector to the exit flange and It sounds great , I also in stalled the external IC and made up a cold air kit and added a strainer for the IC.

    Very cool and great write up, but are there any noticeable performance gains going to dual exhaust? I'm thinking the exhaust note is deeper and less bright.

    I'd have to say no gains! It's just for the shock and awe effect

    Probably no gains , but want to see if it could be done on my 12 GTR-215 and like the sound lol.. did not remove the baffle ,but drilled (10) .500" holes in it and see how loud it would be, i can always open it back up and add more holes or just remove it later. I also did the cold air , removed the internal intercooler and installed the external IC. 14/19R prop and Riva rear exit pipes. and building a oil separator now. also rebuilt the supercharger and added a OEM depth finder, ski module , X-package module. I bought the ski from a friend with 80 hours on it and this is my first jet ski and im learning as i go, lol... and thanks Jerry for posting the pics .

    Sounds great! Sounds like it does indeed have a deeper tone.
