Thereof, can a bad muffler affect performance?

Just like you, your car has to not only be able to breathe in, but also breathe out to function properly. Bad muffler probably won't affect performance as much as a plugged catalytic converter(s).

Beside above, how does exhaust pipe affect performance? An aftermarket performance exhaust can free some of the power in your engine. These systems allow for a quicker, more efficient path for exhaust gases to escape. This means your engine "breathes" better, so spent fuel and air exit the combustion chambers faster.

Likewise, people ask, does removing muffler increase performance?

So for most cars, the muffler delete will not add any power. Some cars will gain some power, but generally it's not much, usually under 5 horsepower. However, if you have a car modified for more power, and still has the stock mufflers, then you'll have more gain.

Does changing exhaust affect performance?

Aftermarket exhaust systems can help increase your engines horsepower by being 'less restrictive'. Slip-on exhausts increase performance, but it's got nothing to do with improving engine efficiency. It's simply that most of the time an aftermarket exhaust will weigh less than what comes standard on your bike.
