      2.5 or 3 inch exhaust for 396?

      i have a 396 BB that has 11:1 compression, ported stock heads, 588 lift cam with 242 duration, 750 double pumper, and big tube headers with 3 inch collector. id like to run the exhaust all the way back so should i go with 2.5 or 3 inch? and any opinions on mufflers? im thinking Spintech.

      thanks
      Jesse
