Removed my Borla ATAK and replaced it with an MPE.
The ATAK was awesome by itself but combined with test pipes it was very loud and changed the tone a bit, sounded like a GT350 which I'm not a fan of.
This is the first time I had the MPE combined with just test pipes and the sound is absolutely horrible, quiet like stock until 3k then the rasp hits and it kinda sounds like an angry duck, from 3.5K-5k it has a nice signature MPE "hollow" wail if you're half throttle, if you're full throttle it sounds wretched. A farting machine gun is what my 10 year old describes it.
Stock X-pipe/cats will be going back on tomorrow. It's unfortunate, I had high hopes for this setup after watching some youtube videos, the sound on videos definitely does not translate well to real life.
