Decided to stay home and install the exhaust system in the driveway. If you are doing a complete exhaust system install do not watch the You Tube videos - mainly because those are not 2011 or newer vehicles. The front DPF catalytic converter has to be cut out of the vehicle. No easy way to just twist and wiggle it to come out. Take a sawzall and cut in front of the hangar and the two pipes will just come right out. Also be very careful with the electrical connections when trying to unplug them - very fragile especially the DEF tube. Yep, broke that one for sure...:mad:
I hope that I don't ever have to re-install the factory system as the little sensors and connectors look expensive. Did I say that I am pretty much a bull in a china shop. The front catalytic converter has little grains of catalyst falling out everywhere - which I originally figured was the culprit of my limp mode and non-warranty failure. The last time that I checked it was a $1275 part to replace and you would have to take the crossmember off to do the install. So 3 hrs. labor plus parts = too much for a non-California truck.
The front DPF sensor was very dirty and the rear one came out clean looking. this is a heavy exhaust system so you should have help when crawling around underneath your truck. OH and all the nuts are metric, except for down pipe clamp nut...

You should have asked someone for advice on how to remove your system here. You don't need to destroy your exhaust system. They will come out with a pry bar easy enough.

The cat by the trans is the hard part and if he was not working on a lift its pretty hard to get the cat back section out in one piece. I did mine on a lift and several others and it can be done. the cat is the hard part.

EGR connections???

Since I was not on a lift I could not get the tail section or the down pipe to drop out without cutting them. Truck is running good with new exhaust system installed.

It says that I now need to disconnect the erg harnesses - 2 brown with yellow tab and 1 black with red tab. Where are those located???

Yes, you are the man. Thank you, I would have never found those erg plugs - especially being color blind I am a little leery when it comes to just unplugging things.

I had to do a little dumpster diving for the rear sensor that I was just suppose to unplug the hose lines from. lol Found it and reinstalled.

I have 1,000 miles on the new tuner and exhaust and no codes :)

The truck is running smooth, I have noticed a slight fuel mileage and power increase.

Now, my power steering seems to be going out, as I can't turn the wheel when I am at a standstill. The brakes still work - just no steering. When it first happened I thought that the engine had stalled out. Oh well, I guess once you hit the 250,000 mile mark things are going to start failing.

Update on Torque Tech system. My truck now has 430,885 miles on it and the tuner is still working as it should. I have noticed that using tune 3 seems the best for power and economy. The only con to the system is the screen will sometimes take a couple of minutes to turn on. A cool pro to the system is a couple of weeks ago I was getting on the highway with a Firebird in front of me and after pegging the speedometer at 120mph for about 1 minute the Firebird gave up on trying to pull away from me :)

Sounds like they have improved the aerodynamics of the newer trucks. My brother's old truck (2003 single cab long bed) would start to lift off the ground around 135 MPH :eek:

I've been to chicken (or too sane?) to take mine over 128 MPH, but being a crew cab short bed, I suspect it would go a bit faster before lift became a problem.

Interesting that the front cat appeared to be disintegrating and plugging up the DPF. I wonder how long it would have taken a dealer to figure that one out? Glad to hear the tuner is working out for you.

I've never felt any weirdness going that fast. I've had mine to 145mph, smooth as glass.

There was no weirdness, it was super smooth. Went up a small incline, went airborne (free-revved) when the road leveled out, and didn't want to come back down. Looking at the road afterwards, the rear axle was in the air for over 100', from the top of the incline to the black marks where it landed & re-gained traction. Luckily it stayed straight, or that could have been a really bad day.

I'm thinking it was the SCLB's cab-to-bed ratio that was causing the lift. It sucked the bed liner right out of the bed, so I know there was low pressure in the bed causing lift. My CCSB was rock solid and planted at 128, while the SCLB was already getting a bit light at that speed.

If I could find some speed-rated tires that could handle my CCSB's front axle weight (2,280 lb/tire), I'd go wind it up and see what it does, but the best I can find are the 115 MPH rated BFGs I have currently. Everything faster is seems to be rated 2,000 lb/tire or lower.
