I had a custom tune done as well by Pat G and took off V4. Just installed ARH Headers with high flow cats and E85 sensor from dsx tuning this past weekend. Ordered a Vibrant resonator because my ATAK is too raspy for my taste and will update soon on sound.

I have the borla atak with afe power cai. No drone at all and don't notice v4 mode. Borla did a really nice job acoustically keeping drone outside of cabin. Cruising 60, 70, 80mph you barley notice exhaust. Radio on about 20% with a/c you can't even hear it. Passing gear sounds aggressive and I love it. W.O.T. the sound is a beast. If planning on headers later I would prolly think of the touring or S-type. I gained about 25rwhp on dyno before tune on my 2018 Sierra 6.2.
