What pipe

[nitro junky]

Other than the parabolic pipe, what other pipe work well on a MAC 45

 

[gil sonsino]

I tried the Mac .45 nitro pipe: good rpm but loss of torque

Irwin muffled .45: good torque and rpm .but can't turn the saw prop.

Parabolic is the best choice lenty of torque,high rpm and more silent than Irwin.

Saw boat SG 21 /P-45 black head,65% nitro, prop 2160 cup 5.6.

OK, which do you prefer, the original .375 stinger version of the 45 parabolic with the baffle drilled out, or the newer version 45 parabolic pipe with the larger stinger diameter? drilled or other wise

newer version undrilled works best!!!!!!!
