I also installed the new Magnaflow, but had 2 major issues - 1) severe drone between 2,000 and 3,000 rpm, and 2) altered shifting patterns with unnecessary upshifts.
Just curious how your Magnaflow experience has been since you installed it a week ago.
I have since re-installed my stock system....
after the 1st 50 miles, I let it cool down and then tightened all the clamps.
ZERO issues regarding shifting patterns at all. Yes there is more drone than stock, but that is what I expected. I wouldn't call it severe though. Sorry to hear you are having issues
