I did it and I love it. It was going into a flowmaster until the weld on the muffler snapped. Its pretty loud and somewhat ricey but I like to annoy people....especially downshifting and you get the unburnt fuel popping.
Like the title says. I NEED oversized pistons for my MSP. I prefer new but might consider used. Let me know what you have and price shipped to Detroit area.
I was trying to be positive about the situation although it seems there may not be an item coming to you. I guess a response from the OP would answer all doubts.
^^^^^^ are you really in Hawaii? I thought it was weird with the time from full payment sent to today with NO goods received but maybe it does take that long?!?! Hope this wasn't too good to be true but seems as though you may have been duped. :(
