well i've got the new header and exhaust on(OBX/Borla) and now all i need is the flex. im wondering if i'll see/feel any significant change in sound/performance with the FS flex pipe, and if its the best one for the cost(109). i guess you could say it just urks my bones that the only part of the system thats factory is the flex, so i HAVE to have it, thats just how i operate. if there's anything better out there, in the same price range, i'd like to know...late
