EMI Thunder Exhaust System - BB Chevy with SS Hi Performance Dry Pipe

Equipped with our performance dry Stainless Steel High Flow Risers, these are our best performing systems. EMI Thunder exhaust systems are a direct replacement for many stock Mercruiser manifolds in Bravo and Alpha applications with exhaust outlets in the stock location ( if you have existing exhaust outlets, please check our dimensions to determine the correct fit before ordering! We are not responsible for exhaust systems that do not match up to existing holes in your boat's transom).The long dry risers on these systems area must with High Performance camshafts to prevent reversion (water ingestion). Standard length on these risers is 32" but they are made to order and can be built to a custom length at no extra cost (unusually long applications may require an additional charge). For custom pipes provide us a mock PVC example showing length from your front cylinder head bolt to the end of the tailpipe (See Mock-up Example images) With dry risers, the engine discharge water and exhaust do not mix until the very end of the tailpipe, outside of the boat, reducing the chance of reversion. They will be quite a bit louder than a standard set of risers.
