Yes. Cats on.

Does anyone have dual bullets dumped right after the cab? If not... Is it possible

I'm considering a 3" cat back split side exit mbrp setup. Can't recall anyone going with mbrp. Thoughts?

So it's that loud with one muffler? That sounded damn good.. I'm thinking about getting two so I can run true duals

But I wasn't sure if I should remove the cats or not but if its that loud then probably not

I have the mbrp dual on my 4.6 sounds great when u get on it but doesnt have an idel tone at all compared to a flowmaster magnaflow etc.

You live somewhere that they aren't required or you plan to cut them yourself? Most shops won't do it. To hear dual bullets search darrenws6 on youtube. Had 04 with duals and I believe high flows. Loud and sounded good. You will also throw codes without cats unless you have a custom programer with tune written for no cats. You could also get single bullet with a y pipe after to achieve duals.
