Ok... an update, Today i removed the 2 super turbo mufflers and I'm just running straight pipes now... this thing is 3x as loud ad my old nova, i used to have straight pipes on it... is really raspy.... definately sounds a little meaner... is this because of the split header? or do i posibly have some other stuff done to this engine that i dont know of? or is the 235 just that much louder than the later model 194's/230's ??
