Exhaust Manifolds
Manufactured out of top quality cast iron, exhaust manifolds are designed to flow more efficiently, delivering better engine performance. Over time exhaust manifolds warp and develop cracks, leading to exhaust leaks and possibly exhaust fumes migrating into the operator’s cabin. We have the perfect replacement exhaust manifold for your equipment.
