Two things I wanted to ask about:
1) In regards to the exhaust setup, is the midstream-merge single exhaust a better design than a full dual exhaust for this engine? Also, can you explain the theory behind stepping up the diameter after your headers? I want to learn more about the thought process behind finalizing this design for the N52 because I've been thinking about a full-custom exhaust of my own.
2) Is the 330 DME a better platform for adding a tune rather than just going off of a single tune from a tuner like BPC? If so, would you mind explaining why?
