sevencow Twin Inlet Exhaust Muffler for Cub Cadet & MTD LT/RZT Models — 951-0616B, Heat Deflector Included

sevencow 951-0616B twin inlet exhaust muffler is a direct-fit replacement muffler kit engineered to drop into compatible MTD and Cub Cadet lawn tractors and RZT riding mowers for quieter operation and simple installation.

This replacement muffler assembly is built to match the mounting points and exhaust routing used on many MTD-produced brands from the early 2000s, including Cub Cadet LT and RZT series models. The kit includes the muffler, a heat deflector and all required screws so you can swap the part quickly without hunting down hardware. It replaces multiple OEM numbers, so it’s a practical spare for owners restoring, maintaining, or tuning older garden tractors and zero-turn mowers.

How does this muffler reduce mower noise?

The 951-0616B uses a twin inlet design to route exhaust through two entry ports, which helps dissipate sound energy more evenly and reduces peak decibel levels. Rather than relying on a single passage, split inlets break up and slow the gas flow for smoother, quieter exhaust. This makes long mowing sessions more comfortable and reduces disturbance to neighbors.

• Dual-entry ports for lower peak noise
• Internal baffling tuned for garden tractor engines
• Heat deflector included to protect chassis components from hot exhaust

Will this fit my Cub Cadet or MTD model?

Compatibility covers many MTD-produced brands and model families from about 2001–2010, including Cub Cadet LT1018, LT1022, LT1024, GT1222 and RZT50/54 variants. It replaces OEM part numbers like 01006537, 751-0616B and 951-0616 to ensure a close match to original fitment. Always compare mounting holes and inlet spacing to your existing muffler before purchase for a confident fit.

• Fits specific Cub Cadet LT, GT and RZT series models
• Compatible with many MTD-branded and private-label tractors
• Replaces several listed OEM numbers for cross-reference

What comes in the kit and how hard is installation?

The package contains one muffler, one heat deflector, four deflector screws and four self-tapping muffler screws so you won’t need extra fasteners. Installation is straightforward for anyone comfortable with basic hand tools: remove the old muffler, position the deflector pointing down and away from vulnerable parts, then secure the new muffler to factory mounting points. Note: orient the deflector down and away from the chassis to prevent heat damage.

• Included: muffler, deflector, 4 deflector screws, 4 self-tapping screws
• Simple bolt-on swap using original mounting points
• Installer tip: point deflector downwards away from components

How durable is this replacement compared with OEM parts?

Manufactured for outdoor power equipment use, the muffler is constructed to withstand heat cycles and exposure typical of riding mower engines. While materials and coating vary by supplier, the design mirrors OEM form and function so you should expect comparable lifespan under normal use. Proper installation and mounting orientation also help preserve surrounding components and extend service life.

• Engineered for repeated heat and vibration cycles
• Design follows OEM mounting and exhaust routing
• Includes protective deflector to shield chassis and wiring

Who is this for: This sevencow 951-0616B kit is aimed at homeowners, landscapers and maintenance shops who service older Cub Cadet, MTD and related brand riding mowers and need a reliable, direct replacement muffler. It’s ideal for anyone restoring a mower, replacing a damaged exhaust part, or wanting a quieter running machine without custom fabrication.
