I was wondering what would be the best for a slip on pipe for my Grizz....I am looking for bottom end power the most. I already have a clutch kit but I think a good pipe would wake this thing up some more. I was looking pretty hard at the Penfold HMF pipe with the quiet core insert so that when I go to camp hunting I won't let everything know I am there !
