Cats and mufflers have nothing to do with engine operation

Cats clean up the exhaust, mufflers keep the noise down

You may get a CEL(check engine light) because emissions are not as clean, but if you have at least one Cat working that may not happen
But in either case engine operation would not be effected...........unless you plug up the exhaust
