Is the location of the converter important for it to work properly? I've been looking on the net and I can't find what I'm looking for. I would like to keep using converters on my truck when I put on my dual exhaust but I want to relocate them about 2 feet further back so they aren't tucked in right next to the transmission. Does anyone know the minimum exhaust temp they need to work properly? Or is there a minimum amount of heat they need to work properly? Thanks in advance for any info.
