This stainless steel tube sits inside the silencer outer can, surrounded by the isolating mat (R.297982), and channels exhaust gases from the pipe connection through the silencer while allowing sound energy to escape into the packing material. A cracked, collapsed, or corroded perforated tube causes exhaust gas to bypass the packing, dramatically increasing silencer noise output and risking noise test failure.\u003c\/p\u003e\n\u003cp\u003eFits: \u003cstrong\u003eRotax 125 Senior MAX EVO, Junior MAX EVO\u003c\/strong\u003e and Rotax DD2.
