Description
Water intrusion at the exhaust-to-manifold joint can corrode fasteners, degrade gasket seals, and compromise engine bay integrity—especially in high-moisture racing environments. The WSM Exhaust Pick Up Envelope 011-421 deflects water spray away from this critical joint, extending component lifespan and maintaining reliable performance. A simple, bolt-on solution that protects one of the most vulnerable connection points in your exhaust system.
