Kickin My A** Why?

Well Like i said they are both running the same trans and rearend, and also he is not blowing tons of smoke its about a normal amount I changed the airfilter and put a 6 inch straght pipe on the truck and have seem to have made a ton of extra power. I havent gotten to race the guy yet but he will be out this weekend and we will see what happens. On the other hand after I did the exhaust and filter I raced my girls 1993 Mitsubishi eclipse gs and it did suprisingly well. about 3 lengths.
