building a freeride/racing superjet wat pipe/

[teamcasslake]

ok so i have a superjet with fully ported for freestyle, case porting, ada gridle head with 37cc domes, wiseco pistons, 13/15 3mm cutback solas concord, blueprinted pump, stock taper-bored 38mm carbs, ocean pro spark arrestors, msd enhancer, and maybe some other stuff. so im running a B-pipe right now and i love freeriding and just messing around on the lake, but i also just got into racing and think i want a dry pipe.

so i have been reading and think i want a factory pipe type 4 cause everybody is talking about how it has great all around power and if u set the water lines up and restrict the water right it has awsome bottom end hit to.

so my question is should i stay with the b-pipe or should i go with the type 4 or a different pipe??????

i would try and find a r&d dry pipe, speedwerx or type 9. if i couldnt find on of those then go with a type 4

so i got 2 pretty good deals for pipe choice. i can get a riva freeride or a type 4.

i hear people talking about how they are very similar pipes, if so what are the differences between the 2??

they are basically the same pipe. I have seen where the RIVA seems to fit the hull better than the Type 4 but who really knows......
