magnaflow axle backs. They are quiet but have a decent little rumble. Mine are for sale But really, Most aftermarket will sound aftermarket. Magnaflow mufflers tend to be pretty quiet. Otherwise, you may have to buy OEM

is it possible to use other OEM like Grand Prix or Cadillac CTS or another in the used ?

Spectacle solo V6 G8 Axle Back Solo Performance is OK ???
