Key Features
- Genuine OEM Exhaust Spec: — Manufactured to the original exhaust flow and acoustic specifications for these roller models, so combustion gases are managed exactly as engineered.
- Direct-Fit Replacement: — Matches the original mounting points and outlet dimensions of the RD11A and RD11AEC, dropping into place without re-fabrication or adapter hardware.
- Compatible with RD11A and RD11AEC Series: — Verified fitment for both the RD11A and RD11AEC Hydrostatic Double Drum Vibratory Roller models.
- Restored Engine Performance: — A correctly functioning muffler maintains the designed exhaust back-pressure balance, protecting engine power output and fuel efficiency on the drum roller.
- Emission and Noise Compliance: — Genuine OEM construction ensures the unit continues to meet applicable exhaust noise and emissions standards for commercial compaction equipment operation.
The muffler is a critical component of the engine's exhaust system, responsible for reducing the high-pressure combustion gases exiting the engine into a controlled, quieter discharge. It dampens exhaust noise to acceptable operating levels while managing back-pressure to keep the engine running efficiently. When a muffler cracks, corrodes, or becomes blocked, operators will notice a significant increase in exhaust noise, a drop in engine power, and in some cases increased exhaust temperatures — all signs that immediate replacement is needed to keep the machine running safely and within compliance.
