My 67 with the Indy crate 360,i have tti headers(nice fit!!!) I've always loved the sound of the short glass packs, I'm going to run 2 1/2" do you think you lose power with glass packs over flomasters, or is it just preference on sound?
use most any modern glasspack and you wont lose any power,look at borla,dynatech,dynomax,Magnaflow for alternatives. flowmasters usualy cost alitle power and might cost your mind.
