« on: September 01, 2017, 03:47:16 AM »

Greetings KORIDER!

Does it normal to have a hole below the exhaust?

Every motorcycle exhaust I've ever seen has had a small drilled hole within 2 inches of their joints. I don't know why but they're always there. I'm not saying every exhaust will but every one I've seen has.

I've seen ones in strategic places to let water/residue out in the past.

Complete hear-say:

I've heard it said that it's because of the sulphur used in unleaded fuel as a lubricant. They used to use lead in fuel, but for obvious reasons, they stopped.

Ever notice the rotton egg smell in high powered car exhausts? This is from the sulphur.

Dissolve sulphur into water and you get sulphuric acid.

Burn petrol and you get CO2 and water.

In summary. A hole is drilled to let the sulphuric acid out, so it doesn't eat your exhaust.

Another possibility is if they are purge welding the exhaust, it could be to stop blowing a hole in the weld right at the end when it becomes completely sealed as there needs to be somewhere for the gas to vent. Just a possibility.

simply just a water / moisture drain point. allows the baffles to drain so they don't retain moisture and prematurely rot the exhaust.
