We have developed an exhaust, for the Stage6 R/T 70cc racing cylinderkit. Click on the icon on the left to download our report on the testing of the cylinder.

Test of our 80-86cc exhaust, compared to the 80cc 2fast exhaust. The engine is a complete 2fast engine, slightly tuned cylinder.

The red line is our exhaust, the blue is the 2fast exhaust. Our exhaust had slightly less top power, but the torque at lower RPM was substantially higher.

Test was done by Maxiscoot GmbH.
