You can purchase just the triple exhaust pipes or a complete kit with 4 inch exhaust tips, flapper valves, hoses and clamps. |
Retain the Benefits of THRU-THE-PROP Exhaust at low speeds! The prop blades create a low pressure area at the hub. The low pressure area actually PULLS the exhaust out of the engine! This is very helpful for low speed torque and fuel economy. Thru-the-Prop exhaust should be retained on every MerCruiser for best low speed performance and fuel economy! You can retain Thru-the-Prop exhaust with the Moore Performance Triple Exhaust system! |
TRIPLE EXHAUST The Moore Performance triple exhaust gives the boater a true Thru-the-Transom exhaust system at an economical price. The triple pipe replaces the aluminum exhaust pipe and connects to the Y-Pipe for Thru-the-Prop exhaust and connects to an exhaust tip installed into the transom for Thru-the-Transom exhaust. Low speed performance/fuel economy is retained by utilizing the prop-hubs low pressure area and high speed performance is increased by eliminating high rpm exhaust back pressure. If you need the reduced back pressure of Thru-the-Transom exhaust for maximum horsepower but do not like the increased noise level, installing muffler tips into the triple exhaust system (in place of the straight exhaust tips) will reduce noise without increasing back pressure. With the Triple Exhaust, excess back pressure simply flows through the prop (something mufflers installed in a strictly Thru-the-Transom exhaust system can't provide). |
Installing Triple Exhaust Installing the triple exhaust is actually EASIER than installing Thru-the-Transom exhaust! With Thru-the-Transom exhaust the Y-Pipe needs to be removed and a block off plate installed. This requires REMOVING THE ENGINE! You do not have to remove the "Y" pipe with triple exhaust!!! |
