Jamie, are these rebuildable by the end user? or at 30K miles are they considered used up? Option to send back for rebuilds? I am ready to put in my order for the header, pcv, and mufflers. 30K miles is 3 years for me and I am hoping these can be repacked. Thanks, Tim

 

The Jackpot Carbon mufflers are full rebuildable by the end user, however these mufflers are very densley packed with Silent Sport Premium and this packing should easily go for well over 50K with only minimal loss
