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

Eddie Marine's EMI Thunder Exhaust Systems for 496 Chevy with high performance risers is their best performing system yet! They feature Thunder manifolds with integral water-cooled exhaust dividers and large individual runners for maximum horsepower gains. They're topped with long stainless steel high-flow risers (a must with high performance camshafts to prevent reversion—water ingestion). These systems are direct replacements for many stock Mercruiser 496 manifolds, and the risers are also available in a 3 in. taller version to replace some Merc manifolds using a spacer. The 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.

Eddie Marine Exhaust Systems for 496 Chevy with high performance risers include:

* EMI exhaust manifolds
* Stainless steel risers with 10mm Merc temp sensor bungs
* Oil filter, accessory bracket, and Merc water drains
* Bolts, exhaust and riser gaskets, fittings
* Jumper hoses
* 5-year warranty
