I have the FRPP stingers on my otherwise stock exhaust system. They sound most excellent. I don't believe the '08 Bullitt's exhaust would sound very similar though since the whole exhaust system was designed to sound as much like the car in the movie as possible. I haven't heard an '08 Bullitt in person but I have seen the movie many times and they both are pretty deep and loud but not the same type of sound.
