Slightly pessimistic words of caution:
The manufacturer of the engine (Rotax) has gone to great lengths (money, science, experience/testing) to design a machine that will give reliable (safe) service over an extended operational life - what makes you think that you can do better?
The development of the engine exhaust system (extraction pipes & noise attenuator), is but one aspect of a complex relationship with other components & systems - have you considered the negative impacts/benefits if any, of your "enhancements" ?
The internal combustion engine can be likened to a pump. Air & fuel in/burnt fuel & gases out. You are modifying the burnt fuel/gases out side of the plumbing (gas flow) - what, if any changes, have you made to the inlet side ?
With the exception of a relatively small group in society, the noise emitted by a poorly muffled or straight through exhaust system is considered to be unpleasant & anti social - have you considered the noise impact, of your modifications, on those living within earshot ?
To make any significant gain in the power output of a given engine, you must increase the volumetric efficiency (the ability to process fuel/air). No simple task. In doing so you will inevitably increase, the amount of heat developed by the engine and the pressures being exerted on almost all internal components. These will need to be managed by other changes ( eg increased cooling capacity, greater oil flow, stronger/heavier components) if the engines expected in service life & reliability/safety is not to be significantly reduced.
