I recently acquired a 2001 DS650 and am trying to figure out which exhaust is on it. Any help is greatly appreciated. Thanks!!

 

looks like a old ct.could be a few brands,a lot of companies were using the supertapp disc system.i dont think its a suoertrapp system though because they hadthe silencer body bolted to the reverse megaphone and not as a solid pice like your is.could be a graydon system too..who knows..lol

 

Thanks for the Reply. My main question is if it is a stock pipe with endcap of if it is aftermarket. The bike also has a k&n with no airbox lid and I found the stock 165 main in the carb. Now I would like to know if that us a stock or aftermarket exhaust so I may jet accordingly. Thanks!!

 

no thats not a stock exhaust.it should have been rejetted running the k n and no airbox lid.i know supertrapp used to advertise how the jetting can be richened or leaned out by varying the amount of disc used.less disc is richer(and quieter)while adding is the opposite.I would still bump up the jetting a tad,youll be surprised what it could do.Most people dont fiddle with stuff cuz it runs good as is and they are happy but that exhaust with your opened up airbox rejetted accordingly should run strong.

 

Its a power pros, older design. I have one, works pretty good. Its a true reverse cone. They make exhaust for several companies.

 

they also make the lt500 quadzilla pipe for trinity..they do make a lot of pipes for people
