What did you do to your NBS GMT800 Tahoe/Yukon Today?

Finally got the cold start vid.

How about a '98 Sierra with dual exhaust? (My dads truck)

Nice deep tone. Is it a flowmaster?

Haven't done an oil change since I bought it @181k. Dealer sticker said bring it in at 185k, I'm at 183.5k and had already put 2.5 qts in it. Not sure when exactly they changed it or what they put in. I just added parts store cheapo to hold me over.

Added half a can of seafoam to the oil and half to the fuel today when I got home. Let it idle for about 20 min with some revs. Then drained and filled with 6qts 5W-30 full synthetic Mobil 1, STP additive with leak guard (figured I'd try it since I'm burning some oil), and a new Delco filter. Feels good to have some piece of mind and now I can really gauge how much it's burning.

The ATP stop leak has been most effective for me compared to STP and others

I think those we're stock on the older Denalis.

for what ever reason, and depending on who you talk to, when the switch is made from conventional to synthetic, the engine "uses" 1-2 qts of oil for the first few changes. After that, it normalizes, or whatever, and now my truck doesnt use or leak any oil. I drain 6qts out, and put 6 qts in every time. (then I dump it all over the driveway... ugh)

Shit!

well, time to find a leather shop that feels adventurous!

Back when GM actually spent a little money to make these trucks nice and worth what they cost.

My dad is not sure, but the mechanic told him the sound would get better with age.
It is setup as true dual exhaust, and the mufflers look like factory style mufflers.

I plan on eventually getting the same thing on my Yukon XL.
