I've seen a few videos on Youtube showing people ovalizing their flex-liners themselves? Is this okay to do?
I have a short section of Z-flex(Novaflex) 5.5" that needs to fit through the damper opening of 4 3/4".
Some companies offer ovalizing and expensive ovalized parts so I am wondering what the experts opinion is on ovalizing liners?
