The reviews on American Muscle seem to be good. Someone said you 'might' get a check engine light using these. I run the BBK 'shorty' catted x-pipe because I have long tube headers. I've never got a check engine light but my tunes are the older ones and maybe they have my rear 02 sensors turned off. I'm not sure. I know now, Tuners can't turn off the rear 02 because of changes to Federal Laws

I've had my BBK long tube headers and the BBK shorty catted x pipe for around 9 years. I only have 38,800 miles on my 2011. I believe they have been on for 28,000 miles (guess) 
. My tunes are the older MPT ones where they could turn off the rear 02 sensors. They can't do that now because of changes to the laws . We don't have smog test where I live in Tennessee. As far as I know my cats are working fine and I run a MPT Ghost Cam Tune for a few days every year that is supposed to hard on the cats. Mine seem to be doing good
The front 02 sensors aren't the problem that cause the check engine light to come on, it's the rear 02 sensors that cause the problems.
Your going to feel a lot of extra power after you install the long tubes and catted x pipe
