Eddie Marine EMI Thunder Exhaust System for 496 Chevy with High Performance S-Pipe Risers

Eddie Marine's EMI Thunder Exhaust System for 496 Chevy with high performance S-pipe risers offers the perfect solution for existing exhaust flow below swim steps. Featuring stainless steel high-flow risers, these EMI systems enable the exhaust to exit underwater at idle—keeping them quiet when you want it most. Adjust the outlet position by changing the length of the exhaust hose connecting the riser with the exhaust bend. The 16 in. long risers are a must with high performance camshafts to prevent reversion (water ingestion). Eddie Marine EMI Thunder manifolds are hardcoat anodized (except polished version) to military spec to prevent corrosion—and come standard with black Fusioncoat finish, with optional finish colors available.
