Noticeable difference ?buy a C4 chamber!
So is the Octane chamber even shorter than the mod...? I just got a rough measurement on mine while in the ski at about 24 1/2" to 25" long.
Got the mod and compared it to the octane. Length seems the same and the only difference is the stinger- the octane chamber has a second tube welded on over the stinger tube that the mod has, so it requires a slightly bigger coupler hose to the water box...
