I use EMI with long risers. Exhaust alone will not get you a big gain on a stock engine maybe 1 or 2 MPH. Exhaust is required for a cam upgrade. So doing the exhaust first is a good idea.

I have a set of EMI Thunder manifolds with stainless risers set up for Silent Choice. $800. Take the Silent Choice and the Y pipe for another $200.

We offer several different brands of performance and stock marine exhaust including Dana Marine and Stainless Marine. Every brand seems to have their own features for different applications. Feel free to give us a call and we can help you pick the system that is right for you.

Check out the online catalog here, first 35 pages have nothing but exhaust systems and accessories.

No new tailpipes or modifications needed with this exhaust, when used in place of the stock 8.1 system, including OEM silent choice systems.

Yes. We introduced a new system at the Miami and LA shows that replaces the stock Mercruiser without modifying or removing any existing tail pipe or sound choice systems.
Installs on 34.5" centers.

Sorry for the poor picture.

One other important item.

System pricing for satin near or at cast manifold levels.
