Posted this question Saturday but it has been lost or got booted. My 885's muffler is damaged internally making it very loud. It looks like all DB models use the same part. After looking here and doing an internet search there appears to be two options, both aftermarket. Both options are available from multiple sources. One claims to be made of stainless, the other doesn't say. I was cautioned to stay away from aluminum? Curious choice for exhaust, especially for a tractor. I recall aluminized exhaust pipe in the past - don't now if it's still around. Regardless, I'm looking for reviews/experiences/suggestions from those who have bought a muffler for their DB tractor.
