The magnaflow will help some. What gearing do you have?

Opening the exhaust won't net you any more torque.

What's your gearing? That's one way to improve the bottom end....a numerically higher gear set.

I would guess you have 3.55's so a step up to 3.73's would be good.

Gears would help you get up in the power band quicker. I think you'll want at least a 3.92if not a 4.10.

There isn't really anything else...except more cubic inches or some form of forced induction.

Call the dealer with your VIN and they can tell you what gears you have. Might be a tag on the differential.

thanks all, like i said going to leave cam and gearws alone until warenty is out, then all bets are off :P i plan on going to a 35 tire and that will bring my bottome end down more, so i will definitally have to look at these when i do the leveling kit with bigger tires

You'll be waiting a long time for the warranty to go out,,, Unless it's somehow different in Canada, the 09's come with a lifetime powertrain warranty,,,,

Now, if you want to speed up the expiration of your warranty, just swing by the dealer with the Diablo hooked up. =)
