How is it going everyone, well i did all search i could possibly could about the Xerd race pipe. And i think i am ready to get this race pipe for my car. However i do have few minor questions about this pipe, & i hope you guys can help me answer my question. First & most does Xerd race pipe really makes any so, called rattling noise once the car heats up. Also is it really neccesary to reset the ecu after installing the pipe. & what if i don't choose not to reset the ecu do guys think this would take longer for computer to automaticly reset, or on another hand do guys think by not reseting ecu, perhaps this may cause CEL . Anyways guys thank you for your help.
