What type of 60 foot times are you pulling? Typically, it's traction that keeps us out of the 12's!

2.2 or a little better, even my best launches are 13's, but my top end seems to go so slow like right before i shift it lags, and as soon as i hit the clutch i can still hear all the exhaust pushing hard

trap speed is the tell tale sign of potential et. judging my the mods in your sig you should be able to get a 12.xx. what do you trap in the 1/8 and 1/4?

that would be your problem right there. get it down to 2.0 or better and you should def hit some 12s

if your car is full weight 107 will get you a high 12(.8 or .9) with a good hook(1.7 60')

unless you do some crasy 6k clutch dumps your 10 bolt will be fine on the nittos...they dont hook that good anyway...

and id most definatly ditch the stock y pipe or what's left of it

Look if you drag race, you are going to break something!!!

Biggest thing is not to go crazy and do something that you'll know will break you car. 5-6K dump will break your stock rear-end.

Things that will hold you back from 12's:

1) gearing
2) suspension
3) tires
4) launch
5) weight

If you have L/T, why would you put 2 1/2" piping on it?

How far do you what to go with your car?

I don't think the catback is hurting the potential much (unless it's a stock catback, in which case swap in an aftermarket one). The 60 foots are what's hurting you, and if the car hasn't been tuned, there's more right there. My Formula (granted it's an auto) with only a lid, FTRA, a flowmaster catback and tuning has run 12.90's in good air, and you have more done than I do. If you're banging the gears and get some traction, you'll should see 12's. As David said, racing breaks stuff (especially on rear ends), so considering adding a rear cover girdle to the 10-bolt as that will help take some of the shock.

Good luck!
