people thinking about downpipes. if anyone desires a downpipe without a cat, i have one off my old gxp. collecting dust. why? because i don't have an ls4 car anymore.
im tired of looking at this thing.
either you can buy it from me, or i can take it back out to kurt in topeka {hogan performance}

It's not the converter itself that is the restriction, but the way the pipe is bent at the O2 sensor and the piece of flex pipe squeazes down to just over 2 inches. Thats what causes the restriction. And by the way I have one very simular for sale also.
