Chris! We really appreciate your business, sir! I'm sure you'll love the system. I would love to hear some sound slips after it's installed! As I'm sure a lot of other B6G members would as well! Either way, thank you for your support! Feel free to reach out anytime! Cheers!

I'll have to check with our media team as I am unsure if we have this en route to test on our First Edition. I have asked a few of our customers that have purchased this to kindly post some videos once installed. So, hopefully we can get some clips in this thread soon!

Thanks for the purchase! Glad you're happy with the sound.

Although, as far as the bracket goes, you should have access to the other side of those studs where there's a non-welded nut and you wouldn't have to cut anything. Although, it does require the removal of the rear bumper cover, it comes off fairly easy with the removal of 6 bolts.

We had to do it on one of our Axle-Back installs :

Ahh ok, thanks. Would have been nice if flowmaster would have that in the instructions. Video makes it look so easy lol.

Hello @LethalPerformance ! (Joe),

Forgive my ignorance here and maybe provide some clarity?

What is the major benefit of the Cat-Back vs. the Axle-Back on the Flowmaster FlowFX?
If I read correctly max HP gain is 17 with the Axle-Back and 12HP on the Cat-Back?

Thanks!

Catbacks will replace all the piping from the midpipe back - this is often seen as a benefit as it is (typically and also in the Bronco's case) replacing smaller diameter OEM piping. There is usually a change in acoustics as well which is also the case for the Flowmaster (Bronco) setups.

Holy crap, so it wasn't just me lol. I had this same issue and you're right, there was nothing stating this. Everything is installed now and it's pretty loud. I'm still debating if I like it or not, the constant shifting is kind of annoying but it does have a nice deep rumble.
