EXCESSIVE ENGINE/EXHAUST NOISE

Probably the most obvious indication that there’s something wrong with your exhaust is excessive noise or a distinct change in the tone of your exhaust. This could be due to a rusted muffler, cracks in the pipe, or a leaking manifold gasket. 

Anywhere that your exhaust system has been compromised will emit a loud, growling type of sound. This should not be ignored for a number of reasons. For one, you’ll lose performance and experience reduced fuel economy. You also run the risk of being fined for having an excessively loud exhaust.

REDUCED FUEL ECONOMY

A less obvious sign that your exhaust is not performing at its best is a noticeable reduction in fuel economy. Of course, this could be due to a number of factors, but it’s a definite symptom that your exhaust might be underperforming. The reason is your engine has to work harder when the exhaust is failing, causing it to burn through more fuel.

SLOW ACCELERATION

If you find yourself having to plant your foot down further and further on the accelerator to extract power from the motor, particularly on take-off from a standing start, then this is also an indicator that your exhaust system could be failing to work properly. This is often due to a leak somewhere in the exhaust, and maybe a leak that’s small enough not to emit a lot of noise.
