Re: x pipe on a 2014 srt
Yes the X-pipe increased my power for sure, no Dyno, but dyno. I'm confident as I was expecting a loss so I don't see there being any placebo effect.
It's currently for sale along with my Borla ATAK, however there is a guy in Florida that has dibs on it if he doesn't get a GTHaus. I'll know when I get back from China in a week.
All in all I feel like I had more power with my custom setup than I do with my GTHaus.
