2008 Yukon Denali, 135k miles, part 2!!

Once I get the Yukon stable I'll do the other car.

Long tubes and a tune on this is good for 500hp at the crank.

Given my track record that should only take a few months....

Open headers test. WIN! I tried to scare my dogs and make my wife mad, but she was spinning the Kitchen Aid so she tuned me out. Nice work man.

Nice work to you too! Trust me, it wasn't worth the pissed off wife.

Yea, mine has some thing completely different than the 2 bolt connection. I cut it off my old ypipe (cat) and had it welded to the ypipe, I had a buddy replace all the slip fittings with vbands. I can pull it out without having to take down the xmember

Thats really smart to get the vbands.

I also need to find a way to get a cat on. I'll still tune out the rear sensors but the environment, yo.

I made my own from spare parts. No ragging on my welds.

'07 and '08 1500s have the two bolts at the end of the Y, 2009s and on use the clamp.

I fired it up. Sounds pretty nasty. Hope not too loud. I think some of the sounds were from not tightening the bands enough. Stock muffler with resonator delete fwiw.

I'll button things up here and there throughout the week.

I heard back from Speed Engineering. Turns out the 6.2 application is part of the "May require cutting and welding" warning. There is only the one adapter in the kit.

No worries. Speed Engineering was responsive, helpful, and cheap!

We had a MASSIVE storm rolling in last night. Hail and tornadoes were reported. Sky turning green and all that with swirling. Sorry Yukon, the Lexus gets the garage.

I did a marathon garage clean up and finishing of the bare essentials to get the Yukon rolling again. I was drenched with sweat after. I made it seconds before shit hit the fan.

That said I was able to get a short vid this morning of a cold start with some light revving at the end. Man too loud and stinky. I think I'll add a cat.

Also anyone know of short O2 sensors? Does that exist? Driver side I think is hitting the body.

I found a big exhaust leak off the driver's header. I'm sure that's what's making everything so loud. I'll fix tomorrow when it's not so damn hot out.

I'm scoping out some catalytic converter options. $$$ Sigh.
