Close, but no cigar. The Shelby GT350R uses the same even firing V8 sound from the Shelby GT500 and Mustang GT Premium. A screaming flat plane would only mean that the engine is an odd firing one.

To differentiate between the two, even-firing engines have a cleaner and softer exhaust note that never vibrates even on high rpms while odd-firing engines have a dirtier and louder exhaust note that tends to vibrate at high rpms (the exact opposite of the even-firing engine), which explains the Mustang family's engine sounds.
