    What kinda exhaust is this???

    This was on my 00' GP1200R when I bought it. Can anyone tell me what exhaust this is? why is it that I never hear it mentioned here? Is there something wrong with it? Seems like a good idea to lighten up the boat.

    No ic, but I would assume that you are going to post a pic of a stinger from Riva. If you look on the billet coupler between the pipe and U-pipe it will have an S-3 or an S-2. If it is the S2 you have a good paper weight. If it is an S3 it is not the best thing for top speed but I loved mine (when I had it) for bottom and mid range punch, plus it makes carb tuning a snap. Either way if you are going for big numbers ditch it and go stock with a D-plate.

    Yup, that's a Stinger from Riva, can't tell what type; it should say on it somewhere if it's an S2 or S3. General rule is that it will cost you 1mph top end speed, but give you more bottom and mid-range. I personaly think you can find your mph with some playing with it, but I can't do any back to back tests with mine. It sure does help with carb tuning, though.

    Looks like a S3. Here is a close up of a S3 with a jetworks valve.

    So how does it detrack from the top end? I am looking for more holeshot and mid-range for riding in rough water. Would my 03' GP1300R benifit from installing one?

    Its a S2 the S3 had water around the collar like in Hydrotoys picture. The one in the other Photo does not. The S1 was welded where it attaches from the U-Pipe the S2 had a coupler I believe this is a S2

    I believe it has something to do with the decrease in backpressure. It will help your midrange more than your holeshot, so if you aren't chasing the top end all the time you can benifit from it. I wouldn't recommend to anyone to spend the money on a new Stinger, but if you have it, it's worth using for the low and midrange. You can also do a very simple Jetworks mod with it, without tapping your pipe anywhere, just change a fitting, route some hoses, and add the Jetworks valve. The Jetworks mod, combined with a pump plug kit and a new impeller, will do wonders for your holeshot, it won't even feel like the same ski. Add a intake grate for better rough water hookup next, then consider some VForce reeds, then you will have a rough water beast.
