The headers had to be dented to get around the oil cooler which I was Ok with. I removed them because the headers and no cats exceeded the decibel limit of several race tracks. My understanding is that no one makes headers that avoid having to do this, even expensive American Racing - is this wrong? Has someone actually installed headers without modification?
