The 'official' word on the RAM-branded cat-back is that it is a no-go, so long past the evaluation stage.
The RAM RACKS are, if not already there, 'apparently' or 'tentatively', destined for the same fate.
The RAM AIRFLOW is, I'm told, still a go, December 1st availability, at ~$1,500.00 Canadian MSRP.
And if anyone is interested, the new full liner BedRug for the '19 RAMs has just been released; BRT19CCK is the part number for the 5'7" boxes. One little wrinkle on that though. You have to remember to get the right installation add-on kit to be compatible with the RAM's spray-in box liner, providing that's what you have.
In the US you can do a factory delete on the spray-in, but here in Canada, at least at this point in time, on a factory order, like mine was, you've got it whether you like it or not!
Frankly, if I could figure out an easy, trouble-free way to strip the spray-in box liner, I would!
In Calgary, The Truck Outfitters usually have very good BedRug prices; talk to Rob Refvik, the Southern Alberta Manager. He can line you up with one of his guys.
Back to the cat-back; MBRP just, in the last two(2) weeks released theirs[P/N S5152304] in T304 Stainless. It's just under $1,235.28 Canadian MSRP. Personally, for the extra few bucks, I wouldn't buy anything but the T304 version.
One caution though, and I did mention this to the MBRP person, the band clamps that they supply are a bit of a challenge, so always be sure to torque them to 80FtLbs, or maybe even go 85-90, it won't hurt. But be prepared to install it, and have all the joints loosen at least once.
After the first retighten I took my truck to a welder friend of mine and had him put a single spot of weld at each of the joints.
When I talked to MBRP earlier this month, they told me that they would be shipping fairly soon, and in fact, may already be. Truck Outfitters again on this one.
As more news on any of these, and other, bits and pieces for the '19s comes available, I'll post it. Or send me a PM.
DISCLAIMER TIME:
I am not an employee of FCA-Canada, or any FCA dealer. I'm just a MOPAR or no car guy. This Longhorn is MOPAR# 61, so I've developed a lot of good in's at Mother MOPAR over the decades.
I'm also not an employee of The Truck Outfitters, just a multi-time repeat customer who
has been treated extremely fairly by them.
