There are a few signs that can indicate a bent motorcycle exhaust:
Visible Damage: If the exhaust pipe appears visually bent or dented, it's a clear indication of a problem. Look for any irregularities, kinks, or misalignments along the length of the exhaust pipe.
Altered Sound: A bent exhaust can affect the flow of gases and alter the sound of the motorcycle. If you notice a change in the exhaust note, such as a louder or deeper tone, it could be an indication of a bent exhaust.
Poor Performance: A bent exhaust can disrupt the proper flow of exhaust gases, leading to reduced engine performance. You may experience a decrease in power, sluggish acceleration, or difficulty maintaining higher speeds.
Exhaust Leak: A bent exhaust pipe can cause gaps or openings between the sections of the exhaust system, resulting in an exhaust leak. If you notice a hissing sound or smell of exhaust fumes near the exhaust pipe joints, it could be a sign of a bent or damaged exhaust.
Misaligned Components: A bent exhaust can cause misalignment of other components connected to it, such as heat shields, brackets, or mufflers. Check for any irregularities or misalignments in these parts.
If you suspect that your motorcycle's exhaust is bent, it is recommended to have it inspected and repaired by a qualified mechanic or an authorized service center. They can assess the condition of the exhaust system and make the necessary repairs or replacements to ensure proper functioning and performance of your motorcycle.
