G'day Grumpy,

I think the pipe is fairly solid. Rusty, yes, but feels like there's still some steel underneath it. The pipe out of the muffler has already been replaced with a lump of water pipe welded in, and as for the muffler itself, as well as the case being rusted through, it sound like it has no guts whatsoever.

You could be right however. If MTD want an arm & a leg for a new one (assuming I can even find one) it may be worth getting hold of some exhaust pipe of the right diameter and making a new one.

Thanks for the clue.

Cheers

Maurie
