Hey
I did this mid to my 2014 1LE, it does make a big difference , as the stock cats are so so
Restrictive, low and mid range pull is way better and very noticeable .
Did you use the o2 extenders on the rear o2"s?
I only had the check engine light once for cat effieciacy below threshold after a hot start

let us know about if you pick up some HP, even seat of the pants. Sounds evil, I've heard that 1/2 the HP gains with LT headers are the high flow or removal of CATS

Next thing you need is a 3-way NPP control switch

I called JBA before i bought these since i have no desire/patience to deal with CEL's. They said get the Vibrant O2 extenders and go with the medium inserts. I have gotten on baby and no Cel's, so it was the right call.

Like i say im in sensory overload with being so happy with how this turned out. It does feel like some extra ummph though. These are completely bolt on and off.

That sounds really good. I'll have to add those to my mods what list.
On that first clip, what motor work is done on that 2014? That thing sounds sick.

Sounds awesome I wanna get them are they easy to install. I'm an idiot when it comes to this stuff but what do u mean by o2 extenders and medium inserts

So whats the hp gain with those ? Seems like a fairly cheap mod and still keeps your warranty in tack.
Is it a DIY or should it be taken in and let a pro install ? dang it sounds gooood !

went to the website and cant find them listed .. do you have a link ?

What's the deal on emissions with these? They have the usual "for off-road use only" disclaimer.

I didnt at first but you need to choose a shorty header and then choose the option of a catted pipe below it.
