This is just a simple mod that disables the flap at the very end of the exhaust, right at the tip.

Also, I have a hard time to believe those who says "the low end torque decreased" using this mod.. These are force induction engines.. You don't lose any torque/power when you relieve the engine from backpressure (even that logic is false but more on that later).. So in short, no I don't feel any change in power, torque or mpg. I also think that the difference in sound is not that noticeable.
