Honda reble 250 cut off muffler to add horsepower?

It is not recommended to cut off the muffler of a Honda Rebel 250 to increase horsepower. While it may free up some flow in the exhaust system, the overall gains are minimal and can actually lead to a loss of power in the mid-range.

However, cutting the muffler will have other negative effects, including increased noise pollution and a potential loss of torque, which is important for a small-displacement motorcycle like the Rebel 250.

There are other modifications that can be done to improve the performance of the Rebel 250 without sacrificing its reliability or practicality. These include installing an aftermarket air filter, rejetting the carburetor, or installing a performance exhaust system.
