20-30 HP tops...not sure about torque. No idea about COBB...but that's my guesstimate.

Save your money, get it Twin Turbo'd

no way your gonna get 20-30 hp with greddy, hfc and cobb. I know a local member that has intake, headers, hfcs, catback exhaust, pulleys and with a technosquare reflash (not exactly cobb but close) and he is pushing 35-38 to the wheels.

Dude 20-30 whp is pretty darn good in my books. You'll be at least in the 370's at the crank, nothing to complain about there!!

Since Greddy is only mufflers, don't expect much from there.. HFC's have been dyno'd and showed +10whp.

Not sure there's a cobb map for your setup, so you'll probably need a custom tune.. I say forget about cobb and get stillen/injen intakes or invest in a full catback

You should definitely get Test Pipes instead of HFC if you want to see bigger numbers and save yourself some loot too

If your going to get test pipes, just get them now so you don't waste your money and have to sell your HFC. Test pipes are cheaper too
