I run Jardine exhaust.
I have their RT99 full system.
Nice power gain, but at 99dB, so it passes event inspections.
For a fuel controller, it really depends on HOW you will be tuning.
If you want to dyno tune, or download maps, or set it up to auto-tune, dynojet PC5 is the way to go.
If you want to tune yourself using carburator logic... that is how the others work...
