Exactly what it should be. I ordered one of these in chrome for my N/A Talladega, and installed it with a cone filter to complete the setup. I must say, for a SAAB, these pipes free up the intake enough to give the car a very nice throaty induction sound.
Inside the cabin of the car there is some resonating at certain revs but that isn't the fault of the pipe, that is the car itself. Nonetheless this is a nice improvement over the stock sound. Especially from the outside of the car.
I also recommend to install a heat shield to stop heat soak with the intake setup, if you are going to delete the stock airbox like I did.
