After post rally technical inspection, the catalytic converter was found to be not in full compliance with the regulations. The catalytic converter was new prior to the start of the rally, but it appears that the substrate was all blown out. We suspect this was a result of a backfiring issue caused by an ignition coil failure.
We have lodged a protest against the decision and we are sure that Rally America will arrive at a fair decision based on the information we have given them.
