Just buy a quality set of shorty headers. Less hassle, will work well.

If the rear diif is a heavier unit, leave it be. If the original was a 10 bolt, I would of replaced it too.

Great idea! I am pulling mine out, they will stay out. Are there any tips to removal? Bolts or body clips? thanks.

Nothibg yet, but come spring...

I want to run a set of these on my 17 Silverado 1500, I also want to run new UCA what brand UCA does everyone recommend?

You cannot run 2 different ratios, they must match. Why would it take so long to rebuild?

Did these changes happen for MY14? Interesting and great ideas. Is the in tank exchanged on the drivers side of the rad? Need to go have a look at my truck once it stops raining.

Look for another brand, ‘mishijunko’ (as my friend calls them) does not always like to support what they sell, quality seems hit and misd. Look at a cooler from a trans company, such as B&M. I thought the V8 trucks had an external trans cooler?

MYC is the RPO code for the 6L80. Another sign of the 6 is a trans dipstick, if it has one, it’s the 6.

I found the GM tool on amazon, real easy procedure.

If I had of went new, was going to get the 2.7, but scored a sweet deal on my truck. Modern diesels are not worth it, unless you are constantly working it. Too much emissions bs to make them worth the $$.

My friend just bought a 2020 Custom, do these need to be programmed to work? Or can he i stall them and use them?

i’m looking for exhaust recommendations for my 17 Silverado. I like a deep rumble, but not noisy/drone in the cab. Im also looking for something that will last, not rot away. What about single vs dual?

Well said. I know quite a few people with MY14 and newer , no issues.

Your issues sound like the 8 speed auto, that has nothing to do with the afm.
