Default 1998 c5 a4 adding headers & 3:73 gears

Does anyone have some insight as to what I could run in the 1/4 mile? My dad has a stock 2012 C6 Auto. Will it be a close race when we go over to Englishtown track in NJ? My mods are below.

3:73 gears
TSP long tube headers w/ hi flow cats
GHL catback
Vararam intake
SLP underdrive pulley kit
180 stat
full street tune

Should be a close race but I think you will take him by a little over a car length if you both leave the same. Your problem may be wheel spin.
Have fun

I think your dad will take you but it could be close. You are still running a significant HP deficit even with the headers, vara ram and the tune. The '98 only had 345hp/350tq while the '12 has 430hp/424tq.

The two extra gears in A6 will help offset the extra gear you have in the rear. There are stock A6 LS3's running in the 11's.
