The difference between LHD and RHD exhaust manifolds for the new Mustang. RHD has had a dramatic change in order to clear the steering gear properly.
The result? About a 5hp drop in peak power over the LHD model. However (apparently) the rest of the engine’s power delivery below peak power is near identical.

Not a big deal anyway if you ask me and a simple ECU remap will solve that if you consider it a problem AND give you more power
Its a problem if you want to mod the engine at all. Those cheap(-ish) headers from a US supplier will now have to be custom built from scratch for considerably more money.
Solution ;)
