Yall fucking retarded? barely used flowmasters are still a great muffler, if you are so set on buying new, then blow the extra money and be happy that you spend the extra money for nothing. Nothing is wrong with buying used flows as long as its in good condition, i guess you morons never bought anything used in your life for fear or breakage or maybe because it could be "tainted". Grow the fuck up assholes and cry on someone elses post.
