no other parts to other than manifolds, Y-pipe, spark plugs and wires and move the heater hose over on the pass side. Drop the passenger header in from the top and driver up from the bottom eazy peezy!

Thanks. I am getting excited about it even though I am at least a year away, lol.

I found it super easy to attack through the wheel wells. Take the liners out and have at it.

If you get a cheaper brand do yourself a favor and them powder coated. That will prevent any issues with rust and corrosion.

A plus on the Thorley's is they're ceramic coated, wouldn't that theoretically help with rust? I don't really know anything about ceramic coating. Though i imagine i could cerakote them through a gunsmith and save versus powder coat. IIRC it will withstand well above 400F. Though i think cerakote has coating designed for automotive applications as well.

Ceramic coating is supposed to be better than powder coating.

Ive had 2 sets of Thorleys ona 2004 and a 2010 ........made good power down low installed very easy my last set on my 2010 are 6 yrs old and the y pipe is rusting it was ceramic coated but the pipe itself is a very thin thin guage ..... the coating on the headers has gone away for about 2" away from the flange at the head on every cylinder and the collectors flanges are rusty ....... IMO the ceramic coating was poor quality the headers are still solid but the coating should have held up way better IMO I do live where we have winters salt etc but that should not effect the headers high up onn the head .......... be nice if you buy these plain steel and get them coated yourself with a quality coating ........ FWIW

Good headers are made from 304 Stainless and will not rust. Buy a good set now and forget about em, or buy cheap now and buy em again later.

Yeah i went to their site to make sure, i was just unsure if he was classifying TSP as good or not. Though it's within my budget and you've had good results thus far. My friend with his camero has had good results thus far. And there are tons of positive reviews out there for TSP. I'm just gonna stick with TSP as planned.

5R had Thorleys on a 97 Tahoe with a 5.7 for 9 years and only had 1 issue with a leaking gasket. If quality is still the same I recommend them. Granted we don't deal with road salt around these parts.

The DT headers are well built and heavy guage so they not a cheap header the Y pipe not so much :(

my 1 st set coating was better ......I would buy again for a 5.3 the tri Y design is excellent for low end increase especially if you tow

Agree but nobody makes a Tri Y design in stainless so if you got a 5.3 and want more low end torque

a Tri Y design is way to go IMO Ive had 4 tube on a 5.3 and changed to Tri Y for improved towing torque down low FWIW if its a race truck with low gears then 4 tube is fine

      Joke Thread

      Fred was in the fertilized egg business. He had several hundred young pullets, and ten roosters to fertilize the eggs He kept records, and any rooster not performing went into the soup pot and was replaced. This took a lot of time, so he bought some tiny bells and attached them to his roosters. Each bell had a different tone, so he could tell from a distance, which rooster was performing. Now, he could sit on the porch and fill out an efficiency report by just listening to the bells. Fred's favourite rooster, old Butch, was a very fine specimen, but this morning he noticed old Butch's bell hadn't rung at all! When he went to investigate, he saw the other roosters were busy chasing pullets, bells-a-ringing, but the pullets, hearing the roosters coming, would run for cover. To Fred's amazement, old Butch had his bell in his beak, so it couldn't ring. He'd sneak up on a pullet, do his job and walk on to the next one. Fred was so proud of old Butch, he entered him in the City Show and he became an overnight sensation among the judges. The result was the judges not only awarded old Butch the "No Bell Piece Prize," but they also awarded him the "Pulletsurprise" as well. Clearly old Butch was a politician in the making. Who else but a politician could figure out how to win two of the most coveted awards on our planet by being the best at sneaking up on the unsuspecting populace and screwing them when they weren't paying attention. Vote carefully in the next election, you can't always hear the bells.

      High Country Suburban build confirmation

      By 3CarSeatDad · Posted

      Can someone confirm if the GM order workbench terminal is able to validate a custom build sequence:   1) Initialize the Allocation Base: Open a new vehicle build queue, select the 2026 Chevrolet Suburban 4WD, and pick the High Country (3LZ Preferred Equipment Group).   2) Select the Diesel Powertrain: Go directly to the engine configuration screen and choose RPO code LZ0 (3.0L Duramax Turbo-Diesel). Ensure it maps to the MHS 10-speed automatic transmission.   3) Deploy the Seating Swap: Navigate to the Interior Options screen and enter RPO code ATT to replace the standard captain's chairs with the power-release 60/40 bench seat. Because you are not trying to force a separate luxury or air-suspension bundle, the standard, premium D07 Fixed Floor Console remains active. The system will accept this change immediately without triggering a warning message.   3)Apply Heavy-Duty Hauling Capability: Input RPO code NHT (Max Trailering Package). The commercial terminal will automatically bundle the required trailering hardware and software modules to support the diesel engine's maximum towing capacity.   5) Layer the Premium Tech and Glass: Separately add code C3U (Panoramic Power Sunroof) and code UKL (Super Cruise) to the order screen.   6) Run the Final Validation: Click the "Validate Order" button at the bottom of the interface.

      Looking at ordering a '26 WT because I want a std cab, std bed

      Spent the last hour or 2 googling and reading up on the spacer thing. I don't like the loss of thread contact on the slip on spacers, but it appears you can get "extended" lug nuts that reach into the hole of the wheel to get back the lost threads. Looks like the only true hubcentric slip on spacers are at least .375". I'd want as little as I could get away with and don't want to cause other clearance issues going any thicker. Bora seems to offer what appears to be a well made .375" spacer and extended lug nuts. I searched here and did find a couple threads recommending Bora. But not cheap. By the time I buy spacers and lugs, new TPMS sensors, then pay a tire shop to install the new sensors, I suspect I'm going to be in over $400. Thinking about running out and getting some washers to put behind the wheel to see if .375" is enough to clear calipers, turn lock to lock without rubbing, and to see if the wheels/tires look strange pushed out a little. This would just be to check fitment.

      Road Master Active Suspension

      By Core-Lokt · Posted

      Roadmaster makes some quality parts; I have their sway bar. I considered the RAS, but I ended up bagging. I didn't know what kind of ride I'd get with RAS, and the bags have interior jounce bumpers, so I can run 0 pounds pressure. I figured I'd have the best of normal suspension ride with assist on-demand. But it seems you got pretty much the same in one item.
