The back pressure from using a performance exhaust system keeps the low pressure fumes from escaping out of the vehicle. Your straight pipe has no back pressure and allows sound, pollutants, and your gas mix to escape through the exhaust pipe , causing a lower power curve on your engine from the escaping gases. Straight pipes do gain horsepower , but at the expense of low speed torque.
That factor is often overlooked. Sometimes you need a little bit of back pressure for scavenging. If so, then most likely your cars performance will be worse than it is with a muffler because the back-pressure the muffler creates helps give you more low-end power.
You are not going to damage the engine or internals or anything without having the muffler.

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. A larger exhaust changes the shape of the power curve.
It makes it more peaky, but the area under the curve is reduced. Average power is less but peak power is more. Mariela Rolves Explainer. Does straight pipe exhaust increase horsepower?
