One thing that is stimulating interest in the process of eliminat- ing power noise is the fact that the problem is believed to have boen virtually overcome by one of the large manufacturers. Com- petitors are studying this car as they have never studied cars be fore, searching for the clue to the solution. Batter driving is re- garded as merely a temporary remedy, but it is being advocated nevertheless, since it has not been established whether the mechani- cal remedy is something that will be available to present users.
Solution in Exhaust, Suspicion points to the muffler, many engineers, believing that the exhaust gases of higher speed, higher compression engines have placed too great a burden on the exhaust system. This accounts, In part, for the number of muffler changes within the last two years, some concerns having gone from mullers that have served them well for years to types embodying radically different principles of ailencing.
Many experts are surveying the possibilities in insulating the mufflers from the frame, and some owners already have made such a change. The practice is to hang the muffler from the frame by means of metal brackets, but? this arrangement is thought to en- courage the telegraphing of ox- [haust noises to the chassis and, of course, to the enclosed body. Heat at the muffer complicates the problem, but some experiments are being made with composition materials which may overcome this objection.

Many owners have noticed that power noises moderate after a car la broken in especially after it has. been driven 5,000 to 10,000 miles. This is explained by the fact that an accumulation of carbon in the muffler takes the sharp edges off the plats and rounds out the corners.
Preventing Overloading, If the Anal exhaust pipe is not large enough or if it has a peculiar shape it, too, may add to the power noise and cause passen- gera to complain of droning and drumming. During acceleration, especially between thirty and forty miles an hour, this noise may be come a deafening roar. Strangely enough, at higher speeds many
