TimeValve stainless steel is the best choice, particularly if you
intend to keep the car any length of time as it will long outlast the
body (so will factory replacement, probably!).
Avoid aftermarket or muffler shop made ones as you will NOT be happy
long -- the OEM is expensive, but it FITS on the first try, and won't
affect performance. After market parts are mot often junk, won't last
two years.
You definitely have a bad exhaust -- the noise in the back is indeed a
muffler with no interior baffles anymore.
