This happened a month or two ago, and was referred to in my thread about my first recer fly-by.
I pulled onto the Mass. Pike at 3:00 am. after getting out of work, slid over to the left lane, and gunned it past some regular schmo's car. I looked to the right, and on the other side of that car was a new Explorer passing at the same speed I was. He moved to the lane next to me and tried to pass. I dropped it into 4th and gunned it up to 90 or so. He kept coming, so when he caught up I gunned it again.
This continued, in 5mph increments, up to about 110mph, when a terrible sound started coming from my engine. It was going putt-putt-putt with each engine pulse. I remembered that I had a temporary, homemade gasket between my cracked, warped Borla header and my uppipe, and the high speeds must have blown it. I slowed down to 75 and the Explorer kept barreling on. A half-mile later I saw blue lights ahead, and the Explorer was pulled over by a Statie. Although the header had been a pain in the ass since March, I'm sure glad it gave me problems that night! It's now in the garbage.
