It's time for a upgrade! 5.3-6.0

You mean the exhaust kit, the header back kit. O yess, I am anxiously waiting for it.
I have their 2nd batch 1 3.4" headers and will be swapping them for the 2nd batch 1 7/8" headers with collector spikes.

Hopefully it's under 450, if so I'm pulling the trigger like yesterday!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!

Why the 2nd batch if you don't mind me asking?

 

[ezdaar]

1st batch tends to have fitment issues. Second batch any and all problems get fixed.
Might wait for 2nd batch header back exhaust as well. due to questionable fitment with 4L80's and the big 6 speeds.
But don't think I can wait that long, I hate my current exhaust.

Are you rocking a nbs or nnbs or obs?
Never seen an lq4 with a 6l80

im nbs. but remember these kits are for 99-13, so they will see all sorts of combo's
there are alot of OEM trucks running around with 5.3's and 6L80's.
GM finnaly got smart and dropped the pos 60 series trans from its truck and SUV line.

I just searched for a 6.0 running a 6l80/90 and didn't see any on pt

 

[ezdaar]

Your correct.
The 5.3 and 6.2 get the 6 speeds.
The 6.0 still gets the 4l80.
