2023 yukon denali 6.2..what to do

[ACHUN717]

Hi All!

Pretty new to the forum and wanted to get some sage advice from everyone here.
Currently have a Magnaflow muffler and KN CAI on my 6.2 V8.
I'm looking to add a couple more mods and these are what I have narrowed down to:

And this might be a dumb question, but do performance headers make the car much louder?

Depends what you are putting after them. If stock setup, then probably not too much change.

I'm going to play devil's advocate and ask why you feel the need to do that on a new vehicle? OEM stuff usually lends rhe best driveability and longevity. It was tried, tested, and approved in a manner to get the most from it while delivering reliability.

The only real way to improve on it is to throw a lot of money at it with programming, deleting DFM (if it's even possible at this point), and then some aftermarket things like you've mentioned/done.

Growing up was always into muscle cars. Loved the sound, just the sound of a beefed up V6 or V8 back then. But had no money to do any of that to my cars. But I guess a simple answer to your question is for pure personal enjoyment!

I still miss my 2006 BMW M5 E60 V10

Dont forget: https://whipplesuperchargers.com/i-2600-gm-6-2l-l87-gen-6-suv-supercharger-kit-2021-2024.html?q=

Wouldn't the above throw some type of CEL w/o any remapping?

I bet that V10 sounded like a dream!
I can only dream of that supercharger lol.

Do you mean the throttle body? From what I’ve read and done research on doesn’t seem that would come on? But I honestly won’t know until I do it..

Same for me on the Whipple...hard to get the green light from the wife lol. If you do the headers and/or TB...please share your findings as those would then be next on my list.

Modern cars are not engineered like they were 10+ years ago where slapping on exhaust and CAI got you 10% more power.

It may be more effective to talk budget and desired gains. I’d bet you get more bang for buck getting a 91-93 octane tune from a reputable shop than anything else.

What do you have on your AT4 so far?
