I have JPA? Long tube headers on my 302. Looking to add an exhaust, what size mufflers should I get? 2.5" Also open to suggestions on brand

If you want "modern" sound you should probably use an x-pipe. The bigger the muffers are the more they usually will dampen. The larger the tube diameter are the more noise the car will make. Exhaust sound is so subjective that it's nearly impossible to make advise, the best is to hear a similar car that sounds "right" and then try to copy that exhaust.
