Finally, with careful consideration and anguish I picked AWE’s catback exhaust over Tubi. The install was just completed days ago and here are my impressions so far:
1. WOW
2. Not too loud, not too soft (i.e. wife didn’t complain)
3. No weird noises
4. Butt Dyno says it makes power. There used to be a little hitch in acceleration between 3000 and 3500rpm. It is now gone!
5. Porsche Tech advised fitment was the best he had seen. No installation problems.
6. Tucks up perfect under bumper.
7. Much lighter than OEM (Sorry, should have weighed them)
No dyno runs
I just didn’t have time
