Looking for easy way to reach 12's

[Ares]

Currently running 13.50(1.87 short time) in 2000GT/5speed
Only mods done are MAC coldair pipe and MAC 2 1/2"catback. I use 275/50-15 drag T/A's for traction. Everything else is stock and not sure what to go with next. I know H-pipe is a big help but which brand does anyone recommend. Also who makes the best long tube headers? As for gearing 3.73 or 4.10 for street/strip car, I'm at a hangup here on this one. Any other items I could try besides superchargers or nitrous would be helpful.

Oh has anyone noticed that with T-45 any gear whine after 3000rpm launches?
