Anybody have any issues with the Moroso Spiral Flow being really loud under 2k with a outrageously loud drone from 1400-2000 rpm? I really thought it would be noticeably quieter then the Magnaflow, but it's just the opposite!This is only the 2nd day having it on the car and the only thing I really like about it is the sound above 2k is a lot quieter then the Magnaflow it just replace. Any constructive suggestions would be great!

I had a Magnaflow #12867 (5" dia. & 14"L case), the only reason I went to a different bullet muffler is because Magnaflow doesn't offer a 3.5" in/out bullet muffler.
