You hope the A/F ratios are the same for both dump pipes, but in many circumstances this may not be the case. Serious race engines use exhaust gas temperature to determin A/F ratios (more accurate or something), & will have 1 sensor per cylinder. It is very possible for 1 or only a couple of cylinders to terminally lean out.
For example, I've heard that with WRXs, with their 2 fuel rails, that with a bit of work & with the injectors really working hard, the 4th cylinder can lean out 'cos there's just not enough fuel making it to the 4th injector. WRX go bang now.
I'm nor saying it's heaps bad or anything, I've seen/heard of plenty of people doing it, it's just that you can have different A/F ratios for different cylinders, & this may cause probs. The other solution is 2 O2 sensors, or a heated sensor mounted further down where the 2 go into 1.
