Just got a 40 series put on yesterday, 3.5" tips. Love the sound. Not obnoxiously loud cruising through the neighborhood but loud when you get on the throttle. Love the low rumble. V4 drone is there but way overblown.. will tune that AFM out soon.

This is what I am doing, except going with a 40 series.

I have used the BG 44k in the past and it seemed to work well. You just pour it into a full tank of gas and run the entire tank. https://www.bgprod.com/catalog/gasoline-fuel-system/bg-44k-fuel-system-cleaner/

He explains it around the 0:45 sec mark of the video. Basically it's the gains in efficiency showing up with better throttle response, better acceleration. Since the top end HP doesnt change much just from the tube, this will be the difference you feel. It is the highlighted area in this picture.

it isnt 20hp to the wheels it is from the curve gain

American Trucks did a video showing the gains from an AirRaid MIT only on a 14 Silverado. Seemed to make a small difference. I am probably going to throw one on and keep my paper filter.

Wish there wasn't so much background noise and wish they revved it up a little more. The only one that sounds notably different to me is the Borla Atak. Cool video.

275 70R18 KO2s on my 2015 Z71. 2" level in the front, no rub.

For those that have had these maintenance items done before, what is the approximate cost for changing diff fluid, transmission fluid, transfer case fluid etc? Im coming up on 45k and want to plan ahead $$ wise. Thanks in advance.

Thanks man! I love the green you really dont see many around, i had a green 06 Sierra that I had to part with when the economy tanked in 2010ish and when I found this one back in January it seemed meant to be!

My 2015 Double Cab LT Z71. 20% tint in the rear windows, 35% front tint. 2" leveling kit in the front with 275/70/R18 KO2s. Also got a Line-X bedliner. Absolutely love it.
