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

[07Burb]

Wow. I just paid $4.27/gallon for 89 this weekend.

Yeah, ours is high but not nearly as high as most people around the country that is for sure. We can't really complain much compared to most other areas....

 

[sumo]

Well you were down to almost fumes, but how much is it a gl there and i assume you got 93 or higher?

normally is about 4.03 in town, but i was in the highway at 4.15. i have a 26 gallon tank. oh thats regular btw

 

[My01yuk]

not sure about sumo but when I filled mine up I put 29+ gallons in it (on a 30 gallon tank ) at 89 Octane which was $3.819/gallon which came out to $112 for the tank.

Oh you have the 30 gl tank. That explains it. I have the 26 gl tank.

Today I ordered some things for my new toy (03 Yukon XL). I ordered a 3 inch body lift, Vision warrior 375 rims, Kelly 285/75-16's, and a flowmaster 40.

Made an appointment to drop the hoe off at the Transmission shop tomorrow.

 

[Splatmaster527]

not really today but this weekend I dropped the front drive shaft and changed the U-Joints (what a PITA) and took off the Tcase motor (thought it was bad but it wasnt so put it back on) changed the front + rear diff fluid and Tcase fluid and got really spoiled by looking at my truck with equivalent to like a 7in lift all weekend since it was on stands...

 

[JBeezy]

Scored a set of factory Yukon 20" wheels with almost new tires in the rear and 70% thread on the front for $400.

Avoided getting another damn ticket.

Still waiting for my Magnaflow....

...Looking at the tracking thing on Amazon they're still preparing it for shipment It's not scheduled to be here til Monday but still they coudl give me some kind of feel good feeling of some sort...I'm not really very patient I guess

 

[nmsyukon]

Which magnaflow did you go with?

 

[07Burb]

Which magnaflow did you go with?

...12589...Got it off Amazon for about $105 with free shipping Really looking forward to getting it put in but will be leaving the following weekend for a nephew's birth so we'll see.

 

[nmsyukon]

Thats the same one i told my muffler guy to order, but instead the 11259 was ordered and put on.

And that's the one that you find to be too loud now? That's the reason why I prefer to order the parts myself. I've been in that same boat before and do not like it at all and is pretty irritating...

Well I ended up with a Magnalow #12289. Works great. The billet grille showed up on Friday. My son and I installed that night. In his 11 year old vocabulary " Dad, that looks EPIC". It does add a nice touch. Cutting out the old was a piece of cake. No going back though.

What's the difference between the 12289 and the 12589?

 

[nmsyukon]

The 12289 is a 5x8x24. The 12589 is suppose to be a bit quieter. I liked my 11259 at first, but it got a little louder after driving it a while. The wife says she is ok with it, so i guess i will leave it for now.

 

[dgould]

Scott is correct. The 12289 is a 5x8 24" case with center in offset out. The 12589 is a 5x11 22" case with the same center in offset out. Who knows if the shorter wider muffler is quieter then the skinny longer muffler?

 

[nmsyukon]

I actually talked to magnaflow support a months ago. The guy told me the 5x11x22 was the quietest muffler they had, followed by the 5x8x24. Who knows if that is accurate though.

Sounds good to me. Awesome info! I'm still trying to get used the "Magnaflow world" cuz I've been in the Flowmaster world for so long On your mufflers, did they just slide into place to be welded (or clamped) in? I know that stock our exhausts have a 2.5" diameter and the size of the pipe on the Magnaflow is 3". I'm assuming that is good so that the exhaust pipe can slide into the muffler pipe?

 

[nmsyukon]

Yes, mine slid right in. At least the front did, since it was shorter than the stock muffler i had to have a little pipe welded in to make the rear ends meet.
