I have beaten this thing down big time and it still is kicking. It works well with my RS12 engine. ONE big complaint is that the angle of the taper and the slick surface makes it not grip the pipe coupler as well as many other pipes. Ie. it slips off the coupler quite easily. No idea about expert drivers.
Also I have no idea about the chambers.
What tuned pipe on the market is best for top-end power? The shape of the Eagle Racing 6.5mm pipe seems to be well-suited for top-end power. It has a gradual-angled divergent cone, short belly section, and a more gentler-tapered convergent cone. That seems to be all the making of a really good top-end pipe, but looks can be deceiving. How would the top-end of the Eagle Racing 6.5mm tuned pipe compare to the top-end of the Novarossi 51603 "top-end" tuned pipe? What tuned pipe have you guys used and noticed the best top-end perfomance?
