Description Technical Specs Warranty Information
 
Equipped with our performance 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 16" long riser on these systems is a must with High Performance camshafts to prevent reversion (water ingestion).  NOTE: Engines using larger than stock, aftermarket camshafts may require a dry tailpipe system to prevent reversion. Provide us with your camshaft's lope separation angle and duration at .050" before choosing an exhaust system! These longer risers WILL NOT work with Selector systems or stock "S" pipe connections. Brackets to keep all of the stock components in their existing locations (shift quadrant, ignition module and oil filter bracket) are available and  sold separately.
