Deere Muffler

I'm wondering if there's a muffler available for my X540. I wear ear protection whenever I ride my Deere, and also when I trim with my Husky 525LK. They are both pretty loud. No hope for quieting the Husky, but if I could silence the Deere a bit, I might be able to lose the ear muffs. They are a nuisance, but I've already lost some hearing from decades in the factory, and my doctor sat me down and gave me 'the talk,' like a dad talks to his teenager about smartening up. So I had to start taking it seriously. I've never heard of anyone putting a muffler on a lawn tractor, but I figured it was worth asking about. A google search didn't give any results.
