Borla catback exhaust

Spangled · July 26, 2020

Has anyone got their hands on the Borla catback exhaust system on the 2020 HD gas yet? It looks like it's backordered thru GMC accessories and the Borla website still has it as "coming soon"? Does it take that long to design an exhaust system or are they just selling out faster than they can make them?

When I contacted borla a while back they said August so I went with the flowmaster kit

how do these things sound on big 6.6?.....i heard 5.3s with exhaust and sound pretty beefy so have to believe even more so on these....any benefits in power/torque, MPG, or just pretty much sound......have to believe there is some performance gain.......there was when i ran them on mx bikes anyway

Here's all I've found so far. Obviously it's not the full catback system though but it is a 6.6

Not sure if just their recording devices suck or what, but I swear the 6.6 sounds better in every clip than the new For 7.3l

Doesn't really make sense why because they're both old style pushrod v8s

Borla has not released the new cat back exhaust yet. Will be worth the wait though. Don’t get impatient and settle

Oh I'm waiting, I'm just wondering for how long. These trucks have been out a year now

It was worth the wait, dealer installed the Borla catback yesterday and it sounds GREAT!

How did you get the Borla exhaust for your 6.6L gas? The website still has coming soon?

I’m curious as well; nothing for the 2021 HD on website.

In mid July the Borla site said coming soon but I had emailed them and was told they were expecting it to be available in early August so I went ahead and ordered it from the GMC accessories site to be shipped direct to my local dealer for install and they received the exhaust the first week of August. Maybe there is a shortage of supply?

Post up a video if you can please. Sure many would appreciate hearing and seeing it.

Checked with Borla and was told “several months”!!! But, GMC accessories sells an exhaust which is made by Borla for the 6.6. Not sure if the version made for GM is more similar to touring, sport or ATAK.
