We're here to zoom in on the aural side of the muscle machine realm. To be more precise, we're bringing you an aural comparison involving the 2017 Chevrolet Camaro ZL1 and the 2016 Ford Mustang Shelby GT350.No, the two cars didn't go head to head header to header - the ZL1 hasn't even reached dealerships yet and no Chevrolet employee would allow for the factory-owned car such as the one seen here to enter a decibel brawl with the GT350.Instead, we're dealing with a melange involving two separate pieces of footage. And since the 'Stand is already out there, pleasing enthusiasts all over America, its side of the comparo also involves real-world acceleration growling.At first, you might say this is an unfair fight and that's because the GT350 badge means the Blue Oval machine is gifted with the flat-plane crank VooDoo V8.The 5.2-liter heart of the Shelby can scream up to 8,200 rpm. Factor in the naturally aspirated nature of the motor and we end up with assets that, in theory, outweigh those delivered by the blown 6.2-liter heart of the ZL1.However, things are different in the real world and that's because certain enthusiasts don't enjoy the high-revving style of the 'Stang. In fact, some muscle car fans have gone as far as labeling the voice of the GT350 as "coarse", which is why the Camaro stands a fair chance in this fight.And, until Ford completes the testing process for the S550-generation Mustang Shelby GT500 (here's a spy video ), we'll have to feast our ears on exhaust battles such as this one.
