Going to True Duals appears to be a good option if one wants to eliminate the heat generated by the OEM cross-over pipe. The rear pipe on the 2-1 systems is not in the same place as the OEM cross-over, but I was wondering if there was much heat felt from this pipe? If I had to guess I would think that the heat issue with a 2-1 system would be less than the OEM but more than True Dual. I'd like to hear from those who are using these systems. Thanks.
