No broken bolts and brand new gaskets as of 15k ago. I do want to see what i can do with porting them though
What did you do to your NNBS GMT900 Tahoe/Yukon Today?

New gaskets aren’t necessarily good gaskets. What brand did you install?
Porting stock exhaust manifolds? For what purpose? And what gaskets did you get? If you’re having sealing problems it might be warped flanges but there are gaskets made to accommodate that. Theyre thicker than regular ones. Also torque values are important as well as re-torquing them at a specified time after install.

They came with the jasper install kit.
I will see about retorque values.
This is the video that covers what I think would be fun modification to do. He gets to it at about 4:45 in the video. Combined with cylinder head porting of course

The Z06 Caliper brackets and assotiated grade 10.9 hardware arrived yesterday. The cheapest and hardest to obtain part of this project is out of the way. Now for the easiest and most expensive! Gotta wait for the pads to wear out on current brakes tho

Makes sense if you're porting the exhaust ports in the heads to port the manifold or get aftermarket ones with bigger ports, but just doing the manifold doesn't

Agreed. There’s a guy on another forum that had an early 2000s Honda Si that had a ported type r manifold on it snd that was actually the first time I’d heard of someone porting a stock mani. Very neat imo that you can do it on these as well
Yes you can port the stock manifolds but like Tom said, to get any benefit you’d need to port the heads too so that would mean pulling them off. Also I think at that point you’d be better off getting shorty headers- they’re pretty cheap. But all that would still only net you probably 20 hp which isn’t really even enough to feel on a heavy truck like ours. But yeah it might be fun just to see. I ported intake and exhaust on some 427 CobraJet heads on my jet boat back in the days and it was a lot of work.

Can they spec a plug for something like a 2009 CTS-V?
*EDIT* Nevermind. I just saw the Ken had the same thought.

Swapped the rear shocks, then swapped the TJ coils back in. Moving on with life...

What rear shocks did you swap to???

A set of Bilsteins I had laying around from my XJ project. I'm updating my build thread with the deets.

I love the no running boards or those door guards look. I really really want to find a nice trail or something to run down. Always looks fun as hell

That's why I like the retractable side steps they are not very noticeable and so far I haven't smashed them on any rocks..

Replaced the passenger side front door handle. Both front handles have broken in the last 6 months. Now I'm waiting for the rear door handles.

Do you notice a big difference? Or do they still feel flimsy/weak?
