T1 Exhaust

I found it interesting the the Owner Manual address intake and exhaust modifications!  It appears that GM wants to make sure you only purchase their Intake and Exhaust upgrades!

How do you think they would really enforce that stuff

When you come in for a Warranty Claim, you can be sure they will look for it!

I think Auto Manufacturers are squeezing every bit of power out that they can, so that is why they would put a statement out like this. 

 

Look at it as kind of a "heads up".

 

There are several other vehicles out now, that with something as simple as an Intake swap, requires a Tune. Same as these trucks now with the GM Performance Intake. Without the Tune, the AFR would lean out too much, and you'd cause damage. 

 

Could also be why there are 0 Aftermarket Intakes out now for these trucks. If you change the Intake, you're gonna need a Tune, and if you DON'T need a Tune, guess what, that Intake isn't and better than the OE one. 

 

Because honestly, even with a complete redesign like these trucks went through, there are always atleast Intakes out either by K&N or AFE, usually, before the Vehicles even hit the Lots. I mean hell, there's not even a drop in Filter that I can find.

Both K&N and Green offer drop in filters. Only mods on my AT4 6.2 will be the drop in filter and GM/ Borla cat back ( both which I have waiting for the truck) until tuning is available down the road.

Where are you finding them? I am only getting Oil Filters for the '19 NBS Sierra for K&N, and the only '19's Green is showing to have things for is the Ram.

Saw the Green Filter at Sema so it may not be out yet but does have a PN. I have the K&N here so those are already shipping.

[DougFL]

K&N has the drop in for the 5.3L

Did you receive your exhaust? and if so, how was the install?

I turned up my home audio system this evening to give it a listen.  At idle, it sounds great, very smooth deep sounding.  During acceleration sounds like it quiets down a little bit.  On deceleration, love popping of the unburnt fuel, sounds awesome.  Think I am going to order it.  Before I do, any more thoughts on the sound as it breaks-in?

That video was right after installation
now that I have run it down the road a bit I really like it
No drone on the highway or city driving (what I do most)
After the cold start at idle can barely tell that it’s a performance exhaust
Now when you stomp on it you can tell it’s a performance motor
