Greg,
I took my car into the War Room for dyno tuning several years ago when I had Superformance pipes on. At that time, the dyno guys rejetted my carb for air/fuel. When I changed to 3" and to 3.5" mufflers/merge collector this year, my air/fuel was still spot on and needed no adjustment. Apparently, this is common since pulling more air out the exhaust also pulls more air at the carb too. Once your air/fuel is set, your good.
Then again, other engines may very.
