It's easy.... first one is a Ford. The one you posted has a 4l60e backing an ls motor in it.... 😆
What did you do to your non-G body project today? [2022]

Just some shots of the fabrication work involved in replacing the damaged sections of my S-10 exhaust system.
The first two shots show the new pipe sitting in the jig that I designed to get all the curves and angles where they ought to be. Under it is the old pipe, which at this point was being used as a reference to get the curve/angle correct.
Shots three and four are close ups of the damage to the pipe that I found while I was engaged in installing the new front brake lines. As you can clearly see from the close up, the pipe metal around about half the bung, and just to the right, or downstream of it, is gone. This is what a few years of Canadian winters and salt brine on the roads do to metal. This was probably the last section of the original exhaust system that came with the truck when it bought it. The engineers and EPA mooks who lurk in the forum shadows will have noted that the bung for the O-2 sensor was placed in the bend. Wrong. The bung needs to be in a straight section of the pipe because that is where the exhaust gas flow is smoothest and most consistent. Bends cause turbulence which messes up the sampling being done by the sensor and causes bad readings to go the Computer, giving it a headache. Net result is a "Check engine" light on the dash for which there is no supporting code, just the computer being antsy because its input is inconsistent.
Here, the new pipe is sitting back in the jig, and waiting for me to clip the short section of the old pipe that has the flange and ring from the donor/dead pipe. You can see it on the bench in the background.
My original redesign for the true dual set up that came with the truck had included provisions for the various sub assemblies to be taken apart if servicing or repair became necessary. In reality, a heavy dose of rust and decay reared its ugly head. The "H" pipe, which also carries the post Cat O-2 sensor was one example of the modular concept that I had tried for. As designed, one end is welded and the other is slip in to assist in the assembly. The slip in end rusted out right at the connection. That necessitated introducing it to my Dewalt 20V Sawzall which is useful for dealing with destruction in close quarters and editing recalcitrant lilac bush branches!
Once I had made the cut, that left me with the two halves and some rehab work. What you see above is the new nipple end that will be getting inserted into a matching hub on the other cat assembly. Right now it is a little long on the basis that it is easier to remove material and sneak up on the final dimension than it is to guesstimate it and then half way through the job, find out that you are either short or long. Long is easier to fix than short.
And at this point the flange section of the old pipe has been already harvested, it and the matching new section of the curve have been trimmed and shortened to fit correctly to each other, and they have been tacked together. The full passes are going to be held off until it has been test fitted into position and the new location for the O-2 bung identified and marked for drilling. It was also at this point that I revisited the angle on the bend and did a thin pie cut from the inside to the outer skin of the bend so that I could relax the bend a little. That got me a better, easier fit back into the jig as opposed to what I had before which fit but needed "encouragement to do it. The easier fit meant that I had a better alignment and that the jig was proving it. For the curious, all the jig actually is, is a bunch or pairs of 1/2 inch angle that were tacked inside and outside, directly to the welding deck. The deck itself is 1/4 plate and not inclined to move around much.
Finally, this is the new spigot that will match that section of new tube that I attached to the H pipe. The welds still need a little more dressing and smoothing but that is about all. The whole business will get a good coat of High Heat Header Paint prior to return to service. Won't help in the long run but will look pretty is someone gets the urge to play earthworm and look under my ride.

I had an Uncle with the same problem. He needed a truck to haul stuff around for his business and his wife insisted that she wanted a car and something large and ostentatious. So he solved the problem by buying a full size Olds 88 or 98 and removing the rear seat so he could install a 45 gallon diesel fuel drum for refilling his equipment!!. Car didn't half reek from diesel fumes but it was one or the other and that was the compromise. I, to this day, still chuckle about it, especially when i imagine the look on her face when he showed up at the house with a brand new high zoot car, only to learn that he had gutted out the back so he could add chocks and a cradle to hold that fuel drum. Snigger.........
Just me wondering aloud here but could you insert a pressure washer wand under the wall of the stairs and flush them out with that? or what about a siphon gun using a long wand and compressed air with the siphon pulling bug killer out of a five gallon pail? Or just back up to the stairs and take a hose from your exhaust pipe and stuff it under the steps and smog them to death.

More kick to the nuts, Allstate wants me to do a power of attorney now when I don't have a title since the bank owns it. Then no instant pay since the truck was in both the wife's & my names. Be 1 to 2 buisness weeks before I'll have money in hand! Then no contact with the bank, only what I got started. Everything else I've delt with in the past was a on site printed check. Need new ride but no one is going to hold a truck until I get that money. I'm glad this is the end with them.
