not kdx related - 2 stroke exhaust question

Post by chadr »

Sorry about the non kdx question, but we all like to talk about dirt bike stuff so here goes...

The flow of the exhaust goes right through the center of the exhaust pipe, so what does this material wrapped around the pipe do? what is the purpose? There is no replaceable packing listed on ron ayers.

It may not show exhaust packing but that is exactly what you have there. Even in a straight through system the packing will make it quieter. To see for yourself remove the packing and reinstall the insert and run it. Then open it up, repack it, and run it again. I'm sure you will hear the difference.
