Exhaust question

My car has 1-5/8" headers, 3" collectors, 3" H-pipe and dual 3" Flowmasters. Right now the motor is a H/C/I - 351W (N/A) making 400-420hp.

My question is - if I weld two 3" to 2-1/2" reducer pipes on the output of the two Flowmasters will my car lose power?

My other question is same exhaust set-up including the reducer pipes on the output of the Flowmasters but with a 418ci SBF (N/A) making 550hp at the crank?

The reasoning by this reducer pipes addition (?) is at WOT it's a friggin' cop magnet. Thanks everyone for your time.
