My car is completely standard, no remapping. I know very little about cars, where is the pipe that kept popping off and how easy is it to get to??
Mine was on the actual elbow of the pipe, had to get it up onto ramps to easily get to it. Its under the heat shield on the right hand side. The mechanic was right in the end, the clip was wrecked - I was there when he changed it and he showed me.
