ok i need help picking out mufflers for my truck. i know its not a big deal but its all about the sound!! i have a 350 sbc with a th400 that i am putting a set of long tube flowtech headers on and am going to run true duals back. i want a good sound but it will be a daily driver so i dont want loud!

i am thinking of dumping them in front of the rear tires but if you guys think that will be to loud then i will go out the back. thanks for the help!
oh one more questing should i run an h pipe? do they really help with power?
