the cat back, system or sub parts, we are free to install on all cars, even smog reg, and tested. (USA)
cat to front is another matter.
my guess is you are not here.
so laws in your country may be different.??
but the engine don't care, nor the engine computer. ECU/PCM
try to keep in mind , most the restrictions are in the CAT.
the muffler flows, do little here, just the sound changes.
you also have an electric motor driven EGR main. (ours runs of vacuum magic,a "horrid" design)
so your EGR wont go dead with cat missing.
