camaro211z28

finally the camaro will be started this weekend. all ive ever owned was lt1s so this is my first old school 350. its a stock 350, i just carb'd it and put a 480 lift 280 dur. cam and dbl roller chain in it. i was just wondering what would sound best true duals or H pipe. ive heard true duals and it sounds nice but never heard an H pipe camaro before. oh and it has shorty headers and im putting 40 series flowmasters on it
