Just saw this thread as I haven't been on this forum much. I was given the "sponsor" title a while back when I was on here everyday and thought I could help field questions for Eloy and assist in sales but even then, the E60 platform was already mature so most questions have been answered.Makes no sense to raise the price on parts that are not in high demand :| A good question for EuroCarFan (Tony ) to answer as he is a sponsor for them on here.
All I can say is I am so glad I got mine for much cheaper back in the day.
Anyway, I actually didn't know the prices went up as I haven't talked to Eloy much either. He did mention his cost of doing business had gone up but it was in a passing conversation. I can ping him to see if he can provide more feedback on this thread.
One thing I would note though is that while no one's happy with the price increase, I think RPI's prices are still very competitive with other vendors out there. I remember when our full catback system was about the price of just an Eisenmann or Dinan section 3.
