Want this question answered?
Some stock pipes have a removeable baffle , others dont . If yours can be removed there should be some bolts or screws at the back of muffler . Remove the screw and the baffle should pull out with a little tugging .
un screw the cap from the exhaust tip ( there will probably be three screws, use in Allen wrench to remove them. when you take that of the baffle usually comes out with it cause its connected to the tip. than sart up the quad and it will be wicked loud. i would run it like this for too long tho. it will ruin the engine.
It will make it sound better and it will give you more power. For an example I made this one hill once but i didnt make it easy when i took my baffle out of my dirt bike I count fly up it and it sounds cool but try not to get mud of dirt in the exhaust after market pipes suck sometimes you have to jet your carborater and you waste more gas.
The stock exhaust diameter is 2 inches
My 2009 stock XR650l maxed out at 95 but I'm gonna add a new exhaust and remove the smog system to help it get up there
While stock diesel systems are very loud they are not the loudest type of exhaust you can get. To get an exhaust that is extremely loud you're going to need to go with the custom or bolt on route.
It is possible to dissassamble exhaust pipes and remove the silencer pipe from inside the exhaust proper. This will, however, make the bike more noisy and thus illegal in many countries. Another way would be to buy other than stock, that is aftermarket exhaust pipes and mount them on the bike.
hollow out the muffler
what year 900 ninja exhaust? If you want stock exhaust for a 1984-1986 Kawasaki GPz900r then I know where you can get them new.
of course not . It will just make it louder . I have a 2003 xr 80 r without a baffle , and it is louder and a little faster than the stock xr 80 , and I've been driving it like that for years and still runs as good as stock . So it does bump up your speed a little , but will let it breath better .
On a stock exhaust, there is one muffler and two tips
