I just purchased a 2006 GT with Bbk ceramic headers with a 3"Magnaflow sytem. It also has the C & L cold air intake with the Diablo tuner. What kind of horsepower gains should I expect these mods to make? Also, I am looking for suggestions as to what is the preferred short throw shift kit?

Are the headers long tube or shorties? What kind of mid pipe? I'm guessing 300-315 RWHP if your running LT's. What kind of tune is it? Is it a canned Diablo tune, or did someone write a tune for you?

MGW or Pro 5.0 for the shifter

Long tube with a custom tune.

Just wondering, but who is doing your tune and are you installing these or are you bringing it to a shop? I am near you and Pro Tree Performance does a real good job, they put my gears in. As for the shifter I like my Pro 5.0, but if I were to have to buy one new and not used then I'd get MGW.

45 hp should be right where you're at depending on your car and the tune. Your results would be 305 RWHP.
