Def was the case with the Milltek on my RS4 and the Supersprint on my M5. After a few hundred miles, they really start to open up. In my exprience, full break-in is at about 2K miles (i.e. sound becomes uniform, exhaust doesn't smell 'funny', etc.).
Gonna be dynoing the full Maddad midpipe and axel-back in mid/late Feb, so will post the numbers. Will do a weigh in as well, should be material savings, the stock pieces are a hog with the extra rear cats, resonator, and overall bigger packaging.
