how much did you lose vs a normal midpipe by adding the xr1 everything else the same.

I want dyno graphs please. Im deciding wheather to take mine out or not. I have to see if it makes my car sound like a rotary again with it out also...sounds amazing right now with the greddy sp and xr1

 

According to my butt-o-meter(non-calibrated), it did not decrease HP(I started with a midpipe and went to an XR1)

 

yeah thanks thats what ive heard I need real proof

 

ttt fellas
