What did you do to your NNBS GMT900 Tahoe/Yukon Today?

[Mrhug3]

Did you have to get a tune with the Lts ?

How much louder did it get ?

Was it worth the price for what you get in gains?

Im looking at this set and was wondering how good lts are on our trucks. I only have an intake and cat back (blackwidow)

Yes, you'll need a tune to get the most out of them, and to shut off the O2 sensors. They didn't make my exhaust louder, just changed the tone a bit. Hard to explain, kinda like having two different sized subwoofers, but you're playing music at the same volume for both. There's definitely a difference from stock, find a set you're comfortable with paying for, slap em in, get the tune, proceed to grin uncontrollably.

Thanks. Yea i get what your saying about tone i just didn't want my truck any louder then it is now haha.

crap..im trying to get all the stuff i can done without a tune then save up for it. I think im already at that point though so i guess ill keep saving for both and maybe a sale will pop up in the meantime...

Lol. The red one is his. It's a Redcat Everest10 crawler. Moves slow, but will crawl over dam near anything with the mods and sticky/ weighted tires. The 32cc 2 cycle Rampage MT( on the stand) and the modded brushless 6s lipo Rampage XTe, he wnt come close too, bc those are fast and expensive (sub $1k stock). His E10 is $149 but he wnt outgrow, or break it unless he happens to do something REALLY stupid.

Tune and delete for cats, yes. Mine has a louder drone inside now. Wifey hates it.

Worth the price of gains, hmm... Not sure. That depends on what you are trying to have at your end goal. It gave me more mid range get up and go so if I get on it around 40-60 I can get up to speed faster. I love that.

All depends on your end goal. But a good flowing exhaust never hurt any vehicle imo.

 

[Drok]

Ah ok. I'm basically looking for more low to mid range get up and go, and since i have to tune anyways ive read a cam would be a better option. Now im getting headaches looking at cam info that i have no idea about i want that lope sound also.now i have lots and lots of reading to do to find one with low end and lope sound haha

@Drok

Maybe hit up @Red Rocket build thread as he is doing a cam and just did the blower on his 02 Denali. I know different years, but he might be able to steer you in the right direction with info and what to look out for. Worth a look anyways. Some great work and killer truck.

Find a good cam company and talk to them. They are car enthusiasts just like us and would love to talk about it.

Been happy with my Range. No shutter and V8 mode all the time. For the quick and easy without a tune, it has worked for us.

 

[Drok]

Yup the range was great i sold it when my buddy sold me his edge tuner

Yes I need to get one .. I'd pull up behind a slow car in the fast lane let off the gas and that split second shutter felt like truck was stalling lol

Returned from my beach trip. I have the Range installed. Truck computer says I averaged 21.8 mpg. This is mainly interstate driving with cruise where I could.

How the hell do you all get such good mileage.....I have mine tuned with BB and still only get maybe 16-17 highway. 18 if I'm babying it. City I average 14.

Will tuning out the afm really help that much? Or do I really need to replace some of the internals to really get it more efficient.

 

[NGAneer]

I'd like to know too. My suspension and tires aren't helping but dang... +21 mpg in the real world? Yes please.

 

[M3kanic]

I averaged right around 19 mpg on the highway when I first bought my 2010 XL Denali. So I could definitely see getting 20+ after a few bolt one and a tune. As long as you could drive it conservatively.
