Depends on what your definition of straight pipe is, some people think its just an exhaust without cats. Other think its just one longggg pipe coming from the header..
But anywhoo, I have an aftermarket exhaust without cats and it sounds fine.
If you were to get literal straight pipes without an actual muffler (the muffler is what helps exhausts cut noise down to low degree) you might run into alot of complaints with people, including some law enforcement.
And for what its worth, IMO, a literal straight pipe on a Z sounds like total crap.
