Pretty cool looking is about it imo. If a pipe of this design has such an advantage, I think that aftermarket companies for major manufactures of 2 stroke power sport vechicles would be all over it. I think it's hocus pocus if you ask me. I could be wrong but imo it seems to be right up there with several other gimmicks offered for nitro engines. All you need is a good plain old tuned pipe designed for your engine and you should get the best performance you can get out of a pipe.
Ill stick with my JP-3 for my big block (Huge power difference) , and traxxas resonator for the small block. I wonder if they make a JP-3 for small block..........
I would say not worth the money. I just don't see it making enough of a difference to make it worth $110. I like THS pipes myself. They work good and not crazy expensive.
