Any one here running their A3 8P catless/straight pipe with stage 2 software? Is it loud? pros/cons?

my roommate used to before he sold the car. couldn't really give you an accurate description since he had an exhaust leak for a long time.

my buddy has the GHL Turboback but changed the downpipe to the ATP which is catless and it sound stupid and obnoxious. He cant stand it and nor can I, it gives a cheap sound that is just very Honda like. I have GHL turbo back resonated and love it, almost no drone or anything. It sounds great and the performance gains from the turbobacks are just insane. Give it a day or 2 to adapt to the ECU and it will pull a lot and the throttle response will increase greatly.
