    Cat 302.5 excavator loud exhaust

    Yes that is the same as the exhaust on it, and I personally picked the parts up from the Milton Cat dealership. It could be a baffle, but the machine was making a similar but louder sound when the old exhaust was going bad. The sound started immediately with the new muffler.

    Cat 302.5 excavator loud exhaust

    I have a cat 302.5 excavator with a loud exhaust. I replaced the muffler and downpipe a couple of months ago. The machine isn't much louder than it used to be at full throttle, but at idle it makes a banging noise kind of. Has anyone else experienced this and or knows what might be wrong?
