Magnaflow vs Borla on the E46 330i ZHP with headers

Battle of the cat-back exhausts! Comparing the Magnaflow 16533 to the Borla 140084.
Car is a BMW 330i ZHP with eBay headers (and ESS TS2 supercharger, LSD, etc).
Both systems are used and broken in after thousands of miles. Video taken using the same GoPro Session 4 on the same stretch of highway. Video for each exhaust system was taken approximately 2 months apart following the same "script".
