I uncorked her today

Sounds good, have fun at the track!

For what it's worth, my car runs with in a few hundredths with or without the exhaust (3 inch pipes with flowmasters that come out right behind the doors)... literally slowed from a 6.92 to a 6.94 in the 1/8 the day I tried it on back to back passes. Open headers were slightly faster, but that could have been because I dropped about 20 pounds of exhaust pipes off the car....you never know till you try it, but a good exhaust system should not slow you down much, if any.
