Did the X-Pipe make my car slower?
As usual nothing has been going according to plan with this car so far. I had originally cut the resonator out and replaced it with straight pipes. The exhaust was immeidately more alive, but more muscle car sounding which is a bit out of character for this type of car.
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 4.4-4.5's with it being 65-80 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?
Here is the data from the app for the heck of it:
March, Today
0-10 .78 .89
0-20 1.56 1.69
0-30 2.18 2.38
0-40 2.85 3.15
0-50 3.67 4.06
0-60 4.57 5.07
