Frequently Asked Questions

What is a 4 into 2 into 1 Exhaust System?

Suzuki engineers pioneered this exhaust system on the DF115A and DF140A outboard motors. The design increases the low end to mid range torque and provides a wide powerband. With an increased volume of air flowing efficiently into the engine, it becomes necessary to increase the exhaust efficiency as well. The 4 into 2 into 1 exhaust system is cast into the cylinder head and block. This race proven technology reduces drag in the exhaust system allowing for a smooth and orderly flow out of the cylinder head.
