Whats the best combination for a faster 1/4 mile for my 03 GT;

- Shorty or Long tube headers
- H-pipe or X-pipe
- 3.73 or 4.10 rear end gears

Btw i got CAI and i also plan on getting chipped and dyno tuned. Thanks

 

1. depends on your emmissions requirements...
2. all sound
3. 4.10 steeper gear=better results as long as you hook up

 

+1 and longtubes if you can get away with it (just to clarify)

 

long tubes- more flow
x pipe gives better torque
4.10s versus 3.73, 4.10s better torque at start, 3.73 better at top end, wont need to shift into 4th at the end of track.
