Recommendations for cordless impact wrenches

[P's_Z]

Hi all, im thinking of getting a cordless impact wrench and would like some recommendations from all you tool gurus. I ask because although ive done research on some options (makita, dewalt, milwaukee, etc) I believe that they may be too powerful for the jobs ill be using it for, with some ranging from 700-1700 ft lbs of tq. Heres some of the things i would like to use the impact wrench for:

removing wheels
suspension work as sways and shocks
brake work and discs and calipers
Exhaust work as removing cats and catback

I dont necessarily need a brand recommendation, but maybe on how much power should i be looking for in a power wrench for the jobs mentioned above.

As always, thanks for the advice
