(888) 312-8812 Login SignupThe Donaldson Exhaust Muffler doesn’t just quiet the noise—it refines it, shapes it, and makes sure the truck’s power is heard without sacrificing performance. Weak exhaust systems choke the engine, disrupting airflow and robbing the truck of its full potential. That’s not what this muffler is about. At 51 inches of controlled exhaust flow, it balances backpressure, optimizes efficiency, and keeps the truck performing at its peak without unnecessary strain. It’s built to survive extreme temperatures and harsh conditions, ensuring it doesn’t just hold up but continues to deliver superior performance in every journey. Choose the Donaldson M100463 today.
