After I saw the performance boost that a high quality pipe did for my engine, I say buy the best pipe you can afford. Personally, if I was racing, I would get a JP3. For all out bashing and what I believe is the best performing RC pipe on the market, I would get a BUKU power pipe. I have a BUKU and it added insane power to my truck. I think the best bang for the buck pipe is a HPI polished pipe, for those on a budget.
