EMI Thunder Exhaust System - BB Chevy With SS Silent Choice Risers - Bright Polish Finish

Equipped with our short performance Stainless Steel High Flow Risers, these are our best performing systems. They are a direct replacement for many stock Mercruiser manifolds in Bravo and Alpha applications using exhaust selector systems or Merc "S" pipes ( 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).
With this system with short Silent Choice risers, we DO NOT recommended them for use with engines with aftermarket camshafts. 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.
