I am swapping pipes on my '07 street bob. Do I need to replace the woven steel gasket?

I looks like I only have about 3/4 of one left in one of the exhaust ports, even tho the dealer just had the pipes off.

Is there a trick to replacing these?

 

Replace em, they're cheap. They are just crush gaskets but the last thing you want is an exhaust leak.

 

cool, thanx
