I recently installed a complete exhaust this weekend on my 996 C2 Manual. Headers, Cats, Mufflers, 02 Sensors. After installing the exhaust I noticed that the new post catalytic O2 sensors were located on the opposite sides of the stock headers. The leads were not long enough to go to the opposite side connectors. What is the best way to extend the o2 wires? Splice in matching gauge wire from the wiring harness? I've read that it's not a good idea to splice into the o2 sensor wires.

Thanks.
