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

      Correct way to service 2024 l8t allison trans?

      By Chuck FB · Posted

      Thanks for that, yes just because I could I measured what came out just to give me some guidance although I already knew to expect it to take at least 9.5 to just throwing in the whole 10 quarts off the shot and doing a one and done heat cycle to drop out the excess to get to the proper level. I don't recall exactly now what I measured that came out but was less than I put back in, I knew I spilled some on the garage floor but the main part was that I was thrilled in the discovery I did not have to touch my exhaust to flex it down. The gasket manipulating is a pain of course to create that clearance to take the pan out and put back in but its all very doable if one is careful and not forcing the gasket to flex too much. From the quote I got at a transmission shop of 900.00 here in Canada ( never asked at the dealer what they charge ) I saved 700.00 doing it myself after paying for the supplies so that to me paid very good wages !, and I knew what fluid was put in and that I had changed the filter and that the level is correct without any doubts.

      first oil change - 2026 2500HD gas

      By Chuck FB · Posted

      Typically its said and I agree so far that the engine oil drain plug oring is not required to be changed out unless you see some damage happening to the oring as apparently the oring lasts well. The dealer I have been getting a few parts from never even stocked the oring but instead stocked the whole drain plug that comes with a new oring which for the dealer is easier because they just throw in a new drain plug if there was any question about damage on it as well and charge the customer accordingly but again only if it is needed.    Also a hint about the drain plug oring to help it last vs a risk of causing damage to it, after its been removed and wiped off or washed off ( that is a whole other topic about some solvents damaging orings because some solvent types do ) to make sure to relube the oring with a bit of new oil so that it won't "grip" on the sealing surface of the pan and needlessly stress out the oring. Its no different than putting some oil on the sealing ring of the engine oil filter. So I just grabbed a new drain plug to have on hand although more recently bought just the oring as well but as its special it costs half the price of the drain plug ... !   Since you mentioned the hate to be empty handed theme, I am not sure what you have in the way of filter removal tools as I like using the exact sized for the filter steel 1" wide band with side to side swivel handle filter removal tool, and it can be used to snug up the filter without risk of damaging a filter as well ( its probably a lisle brand I have ). The drain plug hex size is 15mm and I always like using a 6 point socket if I have a choice and with this truck I've been using just a 3/8 ratchet that has a fairly long handle. Do you have a funnel that will work to pour oil in as that is definitely the short coming bastard part about the design with that fill port on the valve cover on such an angle that no normal funnel will even work. There are adapters and things on the market that will set into or screw into that fill port, I didn't want to deal with US shipping as that is all I was seeing at the time so caved and bought a Lisle brand multi vehicle fit adapter funnel kit and it really works well but there are much less expensive adapters out there that work in conjunction with an off the shelf funnel that would do the job also. Now that I have it, I like how it works and works so slick with the shape of the Amsoil 1 quart containers I have now switched over to. Whatever you do, have a funnel system of some sort as you will be swearing if you dropped the oil and then realize you have nothing to properly pour new oil in without spilling it all over the engine !.     Other comments, quite a bit of oil flows out down the filter when its cracked loose due to the housing above the filter so let it dribble down the filter until it slacks off flow and then remove the filter to create less possible mess. It seems these engines can sit for quite a while and drip and if you have time let it sit there and drip out of the engine as much as it wants. Also a good time to grease the 9 zerks on the front end, that's my typical practice anyway to grease the suspension and steering each time I change the oil. And remember to reset the oil change minder ( not something I am used to doing with older vehicles and equipment ).
