Description
There's nothing like the sweet sound of a well-tuned mower engine, but when your muffler starts rattling, blowing holes, or making your Kohler KS-590 sound like a freight train, it's time for a replacement. This muffler is the genuine OEM Bad Boy part that'll get your zero turn running quiet and smooth again, so you can focus on cutting grass instead of making noise.
What You're Getting
- Direct OEM replacement—fits exactly like the original with no modifications needed
- Proper sound dampening to keep your mower neighbor-friendly and comfortable to operate
- Quality construction that handles the heat and vibration from your 19HP Kohler engine
- Clean exhaust routing that keeps hot gases away from you and your equipment
Built for Real Lawn Work
This muffler is designed specifically for the Kohler KS-590 541cc 19HP engine found on Bad Boy MZ, MZ Magnum, and TSC series zero turn mowers from 2018-2020. These are serious commercial-grade mowers built for cutting acres of grass, whether you're maintaining sports fields, large properties, or running a lawn care business.
Made to Last
Mufflers take a beating from constant heat cycling, vibration, and weather exposure. This OEM replacement is built to handle the demands of commercial mowing operations, with proper internal baffling and heat-resistant materials that won't rust out or blow apart after a season of hard use.
Installation Notes
This bolts right up to your existing exhaust manifold using the same mounting hardware. Let the engine cool completely before removal—exhaust components get hot enough to cause serious burns. A little penetrating oil on the old bolts makes removal much easier if they've been on there for a while.
