Installation Time: Shop Install
Installation Cost: 0-$100

Great addition! I wish all performance vehicles came with this!
This does require a weld job, had a local exhaust shop install it for ~$100.
Shop guy said they were the perfect length to fit inline and that it was an easy install on my '13 GT. I had no issues, I'd suggest asking them to raise your car and show you where they think they will install them if they give you any fuss about it being tricky.
I had FlowMaster Outlaw Axlebacks on it prior, and had them put the stock mufflers on when I had these installed (this is because my reason to get these was to be quiet when I wanted, and loud when I wanted). I've noticed a slight decrease in power in the low end, but it seems like I've got quite a jump in power in higher RPMs.
The butterfly valves have no leaks and sounds 100% stock when closed, they take approx 2 seconds to fully open and then they have a very nice low rumble, and scream when revved.
Very please with this kit, the only thing I would like to change is the switch (not a big deal). It is a momentary switch that you hold down until they open all the way, or hold down until they close all the way. I wish it was a toggle switch so you could just switch to closed or open. Like I said though, not a big deal. Just personal preference.
