One New Aftermarket Replacement Rear Exhaust Manifold Fits Caterpillar (Fits CAT) Industrial and Construction Equipment
This aftermarket replacement rear exhaust manifold is designed Fits Caterpillar equipment powered by the 3306 diesel engine. The Fits Caterpillar 3306 is a 10.5L inline 6-cylinder diesel used across a wide range of Fits CAT dozers, motor graders, wheel loaders, excavators, and pipe-layers. The 3306 exhaust system is a three-section design -- front, center, and rear -- and this part replaces the rear section (9L5521). It collects exhaust gases from the rear cylinders and routes them into the exhaust outlet, making an accurate section match critical for proper sealing and performance.
