Before the flaming begins (you get what you pay for, Save your money and go with a known brand, I wouldn't trust it, etc), I am curious about the design of
these test pipes. They have an anti-reversion chamber in it. I have never heard of anti-reversion and was wondering how this possibly effects the sound of the exhaust as well as performance. If anyone has any knowledge of what the design concept is suppose to do and can further explain it more than "smooth out the exhaust" and "keep exhaust gasses from going back up the pipe" I would like to hear it as I am curious. Might get them just to see out of plain curiosity, but still REALLY skeptical to even entertain it.
