checking you guys what are your thought on it..

30 cc = 1.83 cuin

A Y pipe and two 0.91 4-s muffler after your stock 2-s muffler should be no problem.

A Briggs & Stratton lawnmower sausage type muffler may be a cheaper solution.

Thanks for replying me back..

What about one 1.40 ys muffler

It may work; however, it is 0.40 cuin short in capacity.

Check the link in my previous post for another solution that has worked.

Let me ask one question: as you said it is "0.40 cuin short " i want to know what is the effect on engine if it is short in capacity? will it effect on performance or bad for engine.. as i said power is not required for my project.


Thank you

The DLE will run hot

Keep in mind 2 cycle has twice as many exhaust cycles as 4 cycle does.i doubt that is a large enough muffler for a 2 stroke engine.

yeah what he said...Since a two stroke fires every revolution, the previous exhaust pulse will not be out of a small muffer in time for the next one to arrive.

try a bigger prop like a 20x6 it will lower the rpm, and noise ..it wont have gobs of power, but its on a cub any how

Thank you guys
