    I've just begun working on a 79 390 Auto and have noticed after taking the exhaust pipe off that it rattles due to several pieces of loose thin metal trapped inside. I've gotten most of it out, but some of the larger pieces remain. I assume these are pieces of a baffling system that has broken loose.

    So here's the question; if I get the rest of the pieces out is it OK to use? If not, does the group recommend replacing it with the same pipe, or are there other 390 pipes that don't have this problem and are maybe a better replacement choice. And finally, if I need to replace the pipe, where is a good source for a good used one?

    Thanks for your help with this...I'm new to Huskys and am learning about this cool brand with every piece I remove!

    I think the pipe was double walled on the end closest to the cylinder, people have cut them open and made them single wall pipe. the silencer end is pretty acessable if you take the end off of it.

    Bill -

    Thanks. The double wall comment makes sense because the pieces coming out are curved at about the same radius as the front cone. I'll continue to try to fish them out. If I can't get them all, where should I go for a good used replacement pipe?

    Thanks,

    Look on Ebay, there's always some on there. A friend of mine has some pipes but I think their from a 78 they changed the frame in 79 so the pipe may be different. I'll check with him.
