It is way more than a 15% difference. Decibel figures are a logarithmic scale and not a linear scale. The difference between 102 and 88 is huge! This translates into the race exhaust being about 3 times louder!

For example, OSHA says you can work 8 hrs a day at 90dB but only 1.5 hrs a day at 102dB.

For comparison:
A whisper 30dB
Normal conversation 65dB
Level at where sustained exposure may result in hearing loss 90dB
Power saw at 3' 110dB
Rock concert 115dB
Pain begins 125dB
Jet engine at 100' (loudest exposure with hearing protection, even short exposure without protection can cause permanent damage) 140dB
12ga shotgun 165dB
Hearing tissue death 180dB
Loudest sound possible 194dB
