Too bad this pipe is noe legal for sanctioned events... the 109 bucks are 1055 worth it, it is amazing, easy to tune if you follow the manual, it gives you an incredible range of adjustment posibilities and best of all... you will notice the power difference, its like if you were feeding your engine with NOX.
I am running this pipe in my buggy together with an LRP.28 engine... INSANE INSANE INSANE. I had to use a 7mm carburetor restrictor and tuned the pipe for high speed and even so the car gets launched like a freeking rocket.
Well, it is extremely well built, well thought and the best of all... it really works, it isnt just a crazy idea.
Here is a pic of it in my buggy... well, just a tiny part of it.
