1985 e-z-go loud exhaust
 

I just purchased a 85 e-z-go it has a dirt bike exhaust welded on going straight off motor out the back. When buying owner gave me the original muffler, only problem is I need the exhaust pipe from the bottom of motor to the muffler. Would the Exhaust Pipe For E-Z-Go Gas 2008 & Up, Rxv work with a little fabricating? I haven't had any luck finding original, any suggestions? Bought for the kids to get some early driving training but its a little loud for the City neighbors. Also how much would the stock exhaust quiet it? Is it worth messing with?
