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

She drives. You WILL feel vibration at idle with poly mounts. Things rattle a tad, my bad side mirror vibrates and I can feel the engine through the brake pedsl.

Driving however is completely normal.

swapped those poly mounts on mine over the weekend.... header on the driverside wont even fit back on lol. it hits the mount for the front diff not sure what imma do now. have the set they warrantied i may see if they fit any better

Long story short I failed emissions baaaaaad. I had all monitors tuned to be off. I get to the test and the tech is scratching his head. The ******* poly mounts tipped him off. Up on the lift it went. I played dumb. Super dumb. I blamed the mods on the previous owner. He was nice enough to show me legal parts on his computer. I felt bad wasting his time.

I bought a new drivers manifold and a magnaflow ypipe. Old ypipe was cut out and had cat damage.

$690 shipped. Ouch. At least if I have to stay stock for a while I'll have a good part. So much cheap eBay cats out there.

Poly mounts out, solid h3 mounts in, and stock exhaust installed this weekend.

I like the 2 piece design. Mandrel bends too.

I am so glad we don't have inspection/emissions testing down here in FL. any more.... what a pain.

 

[randeez]

sucks about the inspections, you going to keep modding or throw in the towel?

Why did you take out the poly mounts?

Nah. Just taking a pause. I'll probably slap the long tubes back in soon.

They didn't pass the wife test. They vibrate the cab a bit at idle. Other than that they're not noticeable. I got used to them.

 

[tgui]

Sigh, prepping for tomorrow. Had to get a new drivers manifold because the other had to be hacked out.

At least this dorman piece looks well built! Sniff, not a long tube though.

Pray for tgui.....

 

[tgui]

Sad not seeing the long tubes. Im also sad to see the poly mounts gone.

I'll have it all done tomorrow probably.

 

[tgui]

Also funny is I'll still have my high flow cat in place. I'll be making fewer emissions than when I was stock!!!

 

[kbuskill]

So are you getting rid of the headers or do you plam to put them back on?

In time I'll put them back on. I'll weld in a new O2 sensor bung to avoid hitting the body first.

you lookin for headers kb?

 

[kbuskill]

I thought about it.

 

[tgui]

I had a few minutes. Installed the passenger manifold.

 

[tgui]

Started up with h3 mounts, magnaflow catted ypipe, stock manifolds, extra cat, and magnaflow muffler.

It's so damn quiet and tame.

Oh and you can hear my piston slap when I rev. Ha!

 

[tgui]

Oil change done. Exhaust torqued after heated.

Next up trans cooler lines that are leaking.

Boring shit :-/

 

[tgui]

Next boring job. Transmission lines. Not hard. Just messy and boring.

 

[tgui]

A little trans fluid comes out of the trans itself.

And when the lines are loose quite a lot drains out. Don't be me. Have a pan under it.

Also don't be me. I spilled a beer taking these pics. A nice ipa. I'm not a hipster, just love bitter.

Have a good Friday y'all!
