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

[TheAutumnWind]

Went to a driveshaft place, who said they can't do much until I do something with the y pipe. If I was able to fix or move the y, they'd build a custom shaft, which would be thinner, but just as thick walled, using my old part that goes into the transfer case(forgot what it's called) for what I consider a reasonable price. But that damn y pipe! It's in the way of the prop shaft, along with a header tube. I go to one exhaust place who wasn't any help at all. This is what I'm working with. View attachment 74821Almost hits the tube, and once the shaft is in, the universal will def hit the tube, so it would need to be dimpled. View attachment 74822Can't really tell from this pic, but the y is at least 1 1/2" over the dip in the cross member for the prop shaft. Just plain tight, and I don't want to squash the y, what would've been the sense of getting it if I did that! Defeats the purpose Imo. View attachment 74824Just so damn tight. View attachment 74825

I totally get that you don't want to bash your shiny new Y pipe... but check this out:

Its not going to make as big of a difference as you think.

How did yours compare to that guy with the Escalade that ran the same kit? His seemed to work just a tight fit

Escalade? The one from YouTube? I thought it was a Tahoe. I honestly don't remember.

Na there was some guy on here that replied to some thread about those headers and he mentioned they fit and he had the y-pipe too pretty sure he posted pics so u could see how they fit being AWD it would be a similar fit to yours, it was tight but somehow it fit

Wow! I wouldn't have believed it if I didn't just see it. I wonder if that'll also apply to the y pipe, since both headers merge into the one pipe. Guess I shouldn't really be concerned about singing one or two tubes on the header. Thx for the video.

No problem man. Hope it helps you get it done. They sure had to beat the piss out of their headers to cause a power loss on the dyno, so a couple clearance dents wont be an issue.

Maybe I'll just tell the exhaust guy to dent the y. I just want my damn 4 wd back!

Honestly... that's what I would do.

Think it could crack the y? Because it's right where the pipes are joined with the clamp that's interfering. That's also what the exhaust guy said when I also told him to just bash it for clearance, but not too bad.

If your exhaust guy couldn't handle making that modification and/or repairing a crack then you need a new exhaust guy lol.

I love them for the price. Fit is good.

I read on Amazon were they were cheaply made and the bulbs werent even able to be turned and locked into place. Any of this true?
