I agree pipes are king for engine performance. But they do look stupid with the exit 3/4 of the way near the tail. Even worst when smoke is added. Cans are indeed quiet but do very little for performance. Mufflers are the lightest and some guys will change servos for a 1/2 gram of savings. Overlooking the power to weight ratios saved with muffs for 300-500 rpm on top end. When we fly half throttle most of the time and rant about 1/2-3/4 pull outs with a pipe set up.

To be honest I haven't listen to a set of pipes that have the sound of a screaming 2 stroke that I expect, because most manufactures produce a general pipe and not engine specific or flying style. Each and every combo has pros and cons. Whatever makes you happy in this hobby is right.

Re: The never ending engine thread, East-West

If you look into the world of Bikes and snowmobiles the a "tuned" pipe is designed to change how the engine performs from the manufacturers set-up. These pipes that we buy for our models really aren't anything fancy they just make the 2 stroke exhaust work the way a 2 stroke is intended. Because we can adjust the carbs mixtures is why we can run whatever for exhaust on these motors.

Re: The never ending engine thread, East-West

The only thing with pipes is a high probability of user error. They've gotten a bad rap in the past for causing peakiness or messing up the midrange because guys just bolt them onto whatever headerlength they have in front of them.... Proper headerlength is critical.

Re: The never ending engine thread, East-West

Can I jump in and throw a question on the table?

Is there a difference in how you tune a motor for mufflers, cannisters or tuned pipes? Do you follow the same tuning approach with each type of exhaust system? (I am assuming that the right header length is being used based on previous testing)
