The original exhaust routes like:
Left side under the engine, through cat, out the RIGHT side pipe! Right side exits left side pipe. Cats, dual, hang under engine. You MUST have an oxygen sensor for FI. I modified my existing exhaust, minus cats, so that left side exited left side side pipe. If using new or existing headers/pipes modified, have a 'bung' welded if needed for the oxygen sensor. As close as reasonable to the engine is the best position for the sensor.

New headers from Don (Classic Roadsters II) will need to be modified to fit an oxygen sensor bung.
