3" or 2 1\2" exhaust

[66StangGuy]

i was going to buy some new hooker headders from a friend of mine for $75. the collectors are 3". heres the question. i was thinking of getting the headers and haveing my friends shop install 3" exhaust all around with 2 chamber flows dumped before the rear tires with a H pipe. I think this setup would be good but do you think it will sound good or would i need to go with 2 1\2 pipe? i dont really need much low end torq. and i plan on further upgrades to the motor so temporary power loss isnt a problem. the reason im upgrading is because i dont like the headders i have now and the exhause is stating to fall apart with leaks everywhere.


my other idea was to put the 3 inch pipe in and then install Y collector dumps before the muffler that is just about before the rear tires. then install some type of quiet mufflers for driving to school and by my house. this way i dont annoy the neighbors much and then i can open the exhause from the dumps when i want it loud. does this sound like a better idea? what have you guys done to your stang? whats the best setup you have heard?
