Not sure who's the vendor you order it from but they should of told you that the MXP was a prototype when they were taking pre order. When i got my HKS PROTOTYPE it took 6+ month before the final version was release I'm sure you guys saw this thread i started..

You should of ask the vendor for the ETA and and all the info before doing the Order. I hope you guys understand when someone make a prototype it takes time to get the final version to get release. I know there are some problem with the A/T but this exhaust was never tested on an A/T and now we found out the problem and got it fix, now we are waiting for oversea to get us the new Mid Pipe asap for those that have an A/T on order. If you have a 6MT the exhaust is ready to ship, please contact your dealer for the order.

 

great update Brian!
