Top Speed no longer supplies the by-pass pipes. Circuit Werks still offers them, but is out of stock and is not exactly sure when they will have more. I have installed pipes from both companies and had no problems. They both seemed equal on quality. The Top Speed pipes come in two pieces, which seemed less desirable to me than the one piece from Circuit Werks - more opportunity for exhaust leaks in the two piece was my concern. However, careful installation should overcome that concern. They both are made in China. I found my last set (which was Circuit Werks) on the PCA Mart slightly used. Then I bought a new set of hardware/gaskets from Circuit Werks ($28). Finding a used set may be your only option in the near term or pay $600 for FabSpeed - ugh. Good luck.
