Exhaust Mod Cold Start Comparison - Duelling M3s
I was curious about how the exhaust valve mod affects cold start sound. With 2 M3s at my disposal, my wife and I cranked them up this morning to compare. Inside my car (YAS) the startup was very droney until it settled down. Sounds beefier outside though.
