So I put together an audio vid of the different exhaust configurations I have tried on my 5.7:
1) Stock manifolds with corsa extreme 2.5"
2) Stock manifolds with corsa extreme 2.5" mid mufflers removed
3) SW 2" primary with corsa extreme 2.5"
4) SW 2" primary with corsa extreme 2.5" mid mufflers removed
All were filmed with my Samsung S7 on the floor 12 feet away from the rear of the car and temps at or below freezing (car is in the garage). The last 2 were filmed while the car was sitting 12 inch off the ground. What shocks me is the third configuration is the quietest of them all (I filmed it twice with the similar results). I decided to go with 3 because with configuration 4 the car would backfire like a shotgun from 1-2 if you got on it hard. Also when I would do a cold start with 4 my littlest would cover her ears and yell, Daddy too loud! :naughty:
