not true imo. although i admittidly had trouble with my WEPR fitting, i got money back for the extra cost... and went from 133bph to 155bhp, genuine. With the exhaust and the assisting mods. If anyone says its not genuine i proved it a million times and couldnt care less. The Autofixed dont sound anything special, but look a bit better at the backbox. but are not polished all the way through. And because he lives over here your bound to get good service. The WEPR seem straighter. and better for performance, from what ive seen and heard. these are from when i compared them a while back
