I ordered an FMF 4.1 complete Exhaust system, not cheap by any means. I paid close to $700.00 for it and received free shipping. Two days later I get an Email that another FMF exhaust system has shipped? They accidentally charged me $1500 dollars for two exhaust systems. Wiped out my checking account. It was close to sept. 1 2016, that meant bills are due. I called and spoke to every supervisor I could, some never called me back. I had to wait for them to turn the shipment around and for them to receive the parts back before I was refunded my money. Because of there mistake I was with out the money for almost a week. They did nothing to refund the overdraft fee they caused. I'm still fighting to get it.
