I have a question about what role and purpose does "Chambers" serve in a tuned pipe. I see some manufacturers advertise their tuned pipes as being "Dual-Chambered" or having "Three Chambers", but what effect do "Chambers" have on the performance of tuned pipes? I will be using this tuned pipe for a Rossi Pixi-Black .12 engine in my Reflex NT on a large track with long straightaways and big sweeping turns.
Are "Chambers" designed into a tuned pipe to give the pipe itself better top-end or high-RPM performance, or do "Chambers" give the pipe better "bottom-end" or "low-end" performance? Does a "Chambered" tuned pipe offer better performance than a "non-Chambered" tuned pipe? I am looking for a tuned pipe designed for optimum top-end performance. Will a "Chambered" tuned pipe give better top-end performance than a "non-Chambered" tuned pipe?
I saw this G70319 CEN 3 Chamber .12 tuned pipe at CEN's website. They say it has 3 Chambers to "unleash a good top-end power." Here is a picture of it:
Does more "Chambers" in a tuned pipe mean that the pipe itself will have better top-end power? In other words does a 3-Chambered tuned pipe give better top-end performance than a 2-Chambered tuned pipe?
Also, can anyone tell me if the CEN 3-Chambered tuned pipe pictured above is ROAR legal?
Thanks in advance!
