Does drilling holes in exhaust make it louder?

Is straight piping legal?

Yes, as above, they are illegal. Not because of noise, but because you are changing the exhaust from the factory configuration. If the car had 4 mufflers from factory, it must have the same number in any aftermarket exhaust.

Does a 2 step hurt your engine?

Has your car been backfiring? It can often sound like a gunshot, if not a “cough” or a “sputter”. While an engine backfire (or “afterfire”, if it occurs when the engine has already been shut off) will not harm your vehicle, it can be inconvenient and interrupt any peaceful drive.

This can cause damage to your car’s exhaust or intake if left unchecked — and it also means that your car’s engine isn’t making as much power as it should, and is wasting lots of fuel.

Does cutting off your muffler increase power?

A catalytic converters job is to reduce emissions while a muffler’s job is to reduce noise. 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.

Does a loud exhaust use more fuel?

In short – no. Louder exhaust does not use more fuel. In fact- there’s no correlation between them. A car engine creates combustion to deliver power – which generates a lot of noise.

Do exhaust tips change sound?

The shape and width of the exhaust tip can slightly change the sound to be either more throaty (larger tips) or raspy (smaller tips). Double-walled muffler tips tend to add a full-bodied sound. On their own, though, muffler tips will have a minimal effect on exhaust sound.
