SEAN in CO
This would be 5 star except for the fact that I had to buy a second pack of it to pack my KTM muffler. One pack left me about 4 inches short.

used the manual and watched a bunch of You-Tube vids before doing this maintenance. bike sounds awesome and the packing is doing it's job.

I used it to pack a stock 2002 520 SX-F pipe and it worked great. I would say the noise came down a little but not much. I would buy this packing again.
