i have a jasma muffler on my car. meron sya silencer and I want to try what it would be if it was taken out. di ko lang alam kung pano. meron sya apat o tatlo na screws that seem to connect it to the muff. pero even if i take it off di pa din matanggal silencer. design lang kaya ung screws na un. has any one ever tried taking off the silencer on a JASMA muff. pano kaya? thanks
