Alright guys so iam picking up a 2003 GT Tomarrow, its got 40,000 miles on it, and paint is awesome.. He has Flowmaster 40's on it , im pretty sure there weld in cause the tips look stock.. Do u think wen i put my o/r x on it, it will b louder with the flowmasters, or louder, if i put my magnaflow catback on?
