Just recently I ordered a x-pipe through Vadim and had it installed. The car was immediately almost like stock again. The difference from straight pipes to an x-pipe was night and day. The sound was a bit smoother, but overall quieter. Not exactly my cup of tea. However, I thought the car felt a bit quicker in the lower rpm's, which I was not expecting. It feel like it had more low end torque.

Now here's the kicker. I used the Dynolicious app on my Iphone to measure some 0-60 times. The best time I can get now is 5-5.1 seconds with it being about 90 degrees today. In March I was getting consistent 4.5's with it being 65-75 degrees.

At first I figured it would be the temperature, but I didn't think you could lose .5 second or more. Could the x-pipe be the culprit?
Tezza,
Man, you've been playing with that exhaust forever. Should've left it with straights. Anyways, hope you figure out the problem bro.
