You won't damage the motor. I recommend the stainless. Ace Hardware and Home Depot sell a cylindrical muffler that works well, too.
what does the standard muffler do. what difference would a regular pipe do.so I can just use a pipe bend it to shape and there will be no problems with the engine.
Welcome to the forum Tony 
If ya want that 4-stroke to go fast, make one like this out of steel tubing. It works great but is verrrry loud!

whats the difference between EZMotors Stainless steel flex pipe in the a Stainless steel flxe pipe at home depot or ace hardware store have.I dont want to ruin the motor.
Tony, IME, if you have an exhaust pipe on the motor, you will not damage it.
Operating without an exhaust pipe creates a strong possibility of the exhaust valve cooling too quickly when shut off, and warping.
Some carb setups require back pressure to run optimally, but that won't kill a motor.
