My systems were: 1. Stock, 2. Corsa, 3. MagnaFlow, 4. Modified stock, 5. Borla S.
The best performance was definetly with the Magnaflow. Thats what was on the truck for her 3.48 0-60 and 11.91 1/4 runs. Unfortunetly, the fit was off.
The Corsa sounds incredible, but flowed too well and killed the torque curve.
The stock and its modded version were quiet, but the motor didn't wanna rev.
And the Borla is a freaking beast. It drones like crazy, looks awesome, sounds awesome, and flows good but not too good.
Of course, thats the results on my modded 6.1. Other motors will have different results, due to flow and exhaust system design.
