What would I have to do?

Mr. 5.0: With the modifications you have suggested, how much would American Thunder Flowmaster catback drop the estimated ET? With stock tires what would you expect the 0-60 time to be on an SN-95 AODE.

The catback alone won't do much, less than a 1/10th et drop at the very most as the mufflers are not restrictive on the Mustang - the catalytic converters are.

With all the other modifications listed (3.73, H-pipe, timing, etc) plus (I forgot to mention) underdrive pulleys you should see a low to mid 14-second et with an AOD transmission, a big power-loser in stock form.

0-to-60 mph time should be 6.8 or so. Lot of variables to consider when predicting et and 0-60 times but that's a reasonable guess based on other Mustang owners experience with a SN95 5.0 and the AOD. Your et may vary.
