got mines installed and fitment was pretty good. sounds pretty good w. my borla exhuast and its not that lound also just a bit of rasp but i ain't complaining for the price.
^It's probably better to run HFC's if you have lots of other breathing mods. I had pretty much all the breathing mods and test pipes were the last one to be installed, after that the car kept stuttering and stalling. Definitely needed a reflash, but I took them off instead and put OEM cats on and problems were gone.

basically, his air-fuel ratio was too lean. The reflash will take care of the AFR.
What they said, my ECU was pretty much maxed out for breathing. I had all the breathing mods possible except headers and cams.
A retune would have fixed my problem easily as well as gain tons more power. I already had non-foulers on the test pipes, so that was no problem for any sensors.
