Wouldnt worry if it was silenced or not. Replacement with any k03s will work fine.
A k03 would work fine on a k03s map/engine, providing the intake side hoses were swapped.
10psi on a k03s isnt even a stage 1 remap on a k03. You might just feel the power run out at higher RPM, and of course, you might get a very slight overfuel, but would have thought ECU could cope with that.
