Two muffler-looking units (one of them a resonator?).. One in front and one
behind the rear axle. The front one has developed a loud jangling sound
when idling in gear. I suspect the insides are breaking up.
There are 2 exhaust pipes in and out of this unit and it looks relatively
easy to remove the resonator (?) and replace with straight exhaust piping.
Anyone here done this? Does the front unit have much effect on noise or
performance? The rear one looks as big as a truck muffler and appears to be
adequately sized to be the main sound muffler.
