2014 SLP Panther Camaro: Tunnel Blasting and Decibel Readings

June 10, 2014

2014 SLP Panther Camaro

I love hearing our long-term 2014 SLP Panther Camaro's exhaust note, especially when it bounces off the walls of a tunnel or freeway underpass. I wanted to know just how loud the exhaust on the SLP Panther was so last weekend I downloaded a few cheap Decibel-meter apps for my iPhone and headed for the hills.

For a baseline, I turned to our testing numbers. During Edmunds.com performance testing, we measure decibel readings inside the car, with the climate control and stereo off and the windows rolled up. We take three measurements: one at idle, one at full throttle and one at 70 mph in top gear. Here's how the SLP stacks up against a few other Camaros along with the two quietest cars in our long-term fleet, the 2014 Ram 1500 and 2014 Tesla Model S.


dB @ Idle

dB @ "Full Throttle"

dB @ 70 mph

'14 SLP Panther




'13 Camaro SS (1LE)




'10 Camaro RS (V6)




'13 Tesla Model S




'14 Ram 1500 EcoDiesel




Surprisingly, the SLP is quieter while cruising at 70 mph than a standard 1LE Camaro SS or a V6-powered Camaro RS. In a tunnel at full throttle though, the SLP registered much higher than that. Using two different apps in two different tunnels I got the same number: 100 dB.

There are conflicting arguments about whether the iPhone's microphones can't measure levels above 100 dB, though, so our SLP may be even louder than that. It's also said that anything over 85 dB can cause hearing damage, but for my money, the spine-tingling rumble and roar of the SLP's monster exhaust is worth it.

    IDK, the most interesting thing to me about those numbers is that a diesel equipped pickup truck is quieter at 70mph than an electric car.

    ...And almost as quiet under full throttle.

    You can likely attribute the Tesla's higher decibel reading to tire noise - that's what happens with such sporty tires.

    Sporty tires that are feathered due to goofy rear suspension geometry or "instant torque," according to Tesla.
