So this is my car after adding the fast intentions non resonated test pipes. It's louder yes but not nearly as much as I was afraid of. There is some rasp under full throttle but it's really not bad at all. I imagine with the resonated test pipes there wouldn't be any rasp at all. So things to note, the car made and additional 11whp to a total of 317whp. More importantly saw gains all the way through the power band in the range of 20whp and 15 ft/lbs of torque. Torque was 265.63. I do love how the car has a bit of that growling back fire when I let off the throttle under load. Oh and when I saw a little flame shoot out of the exhaust I had the biggest smile. A/f ratios are spot on. Once I install my Z1 ported plenum and ported lower intake manifold I will be getting an ecutek tune. I'll have dynos for each addition. I hope this helps guy and major props to fast intentions. Their is no one else I would rather do business with.
