New Super40 Flows??

oh btw...i went from older 40 series to the super 40s...incase ur wondering. I also made a custom catback with 3 inch piping after the x to the muffs, then from the muffs back its 3 inched in chrome, no tips...the "tips" are part of the pipes, not an add on
 
the gas pedal feels stiffer, as if it knows its got more power now. Basically what I did by removing the stock pipes and 2 1/4" 40 series is opening up and allowing my headers to push out more exhaust. THe super 40 is great for this because it compensates with added backpressure, but not too much to loose power. I can feel more power, but its not SOTP
