I ordered a part that was wrong and sent the part back as instructed it's been over 2 weeks and I still have not received my refund
Response from Lethal PerformanceMay 13, 2026
We apologize for the delay regarding your refund. We did receive the return authorization from ATI, however we were not provided with the return tracking information that was requested in the RMA instructions, which delayed our ability to monitor and process the return more quickly. In addition, the manufacturer credit notification was unfortunately sent to a different department on our end, which also contributed to the delay. That said, we’ve gone ahead and completed the refund for your order today. We appreciate your patience and apologize again for the inconvenience.

Bought a Fathouse Fabrications Carbon Fiber Cold Air Intake System (2020-2022 Shelby GT500) - FP-GT500-CF-CAI . After purchase was contacted and told you didn’t have the throttle body adapters . Was asked if I would accept the Kong adapter. Not being a CAI expert, I was under the impression I could use it to install onto my Stock throttle body . It didn’t fit so obviously I couldn’t install it . Now going on 2 weeks I’m still waiting for the stock throttle body you guys promised me . Contacted customer support and been getting the run around on when I’ll receive stock adapter . Very disappointed on how this was handled!
