If you're running an Exmark Vantage S-Series commercial zero-turn mower and the muffler has rusted out or been damaged, this is the official factory replacement part. The part number is 135-2578. It's a direct-fit EFI (Electronic Fuel Injection) muffler designed specifically for the engines used in these professional-grade mowers. Using a genuine Exmark/Toro part ensures perfect fitment, proper exhaust flow, and maintains the machine's original sound and performance levels. It's crucial for the safe and efficient operation of your equipment. **Very important note:** Commercial mowers can have variations even within the same model line. Fitment can depend on the exact sub-model, serial number, and production date of your Vantage S. Always, always double-check this part number against your mower's official owner's manual or parts diagram before ordering to confirm it's the correct one. This is a critical component for keeping your valuable equipment running smoothly and quietly on the job.
