parabolic pipe

[gil sonsino]

Is there any difference in performance from the first version parabolic pipe .84 to the new one?

I've been using the last version parabolic .45 & 67 sucessfully on my riggers but today I tried a previous .84 version on my sawrigger and after many trials decided to return to my 15cc Mac nitro pipe.As we are facing problems with noise levels I decided to silent my boats but in this case it was a heck tune the boat.

Let's see if some of you has experienced that!?

Gil,

I think I remember that there was a change to the stinger id. Could be wrong tho' - don't run those pipes myself.
