Columbus..the 1957 IH 4x4..

[mongocanfly]

I wanted all stainless exhaust, so to go with the stainless headers, I ordered everything in 16ga, i got 2-1/2" 409ss tube, along with a assortment of 60deg bends and a couple of 180s,all in 409ss, I'm also using band clamps on the mufflers..also ordered a bunch of isolated exhaust hangers..
the headers came with a bunch of useless (to me) ss tubing..these headers where for a Camaro , so it's part of a Camaro exhaust system..the collectors have resonators on them, so I decided to go ahead and use them as well, the outlet on them is almost 3in so I had to get a couple of 3x2-1/2 adapters , I talked to a guy at the exhaust shop about expanding the 2-1/2in , but he acted like he didnt want to, he said it would split...hes also the guy that wanted $1200 to run the exhaust , not including mufflers..
So this is gonna be a learning experience for me...learning to tig weld ss tube...i did a bunch of practice on the excess tubing that came with the headers...still no expert by any means, but I think itll hold together

Heres my pile of parts..

[mongocanfly]

Got the drivers side mostly done..dont laff to hard at my welds..haha
Still havnt decided what I want to do behind the muffler..I dont want the exhaust exposed any more than it has to be...dont want it hanging out the back or sides either..
Thinking about turn down right behind the axle

[mongocanfly]

The passenger side is gonna be a little more tricky
Gonna have to snake it thru the hole highlighted in yellow..
Its gonna have to have a couple or three dog legs in it to clear everything
Will probably have to use a band clamp in this section..
I dont think I can get it thru there if its welded solid..
Then I'll have to add some heat shields where the fuel pump and reg are mounted

That looks good. Glad to see progress as always.

[Dieselwrencher]

That is looking nice. Great work!

Greg, that is some nice work, will be a great ride when done and on the road. Curious, did you ever order the bench seat cup holder four your truck? Really liking the one I ordered for my '57 bench seat. Works great and does not bother the shifter at all even when doing some rather "spirited" shifting, LOL.

[mongocanfly]

Thanks guys..little by little
Gary, I havnt bought one yet, but it is on my list of stuff to get..

[mongocanfly]

Been getting my 5min here and there..and had to order a couple of 30deg bends to do the 2nd offset behind the transfer case...they sat at fedx in oregon for over 2 wks before they shipped them ..
so I've been getting exhausted working on my tailpipes..got the pass side snaked thru the hole by the tcase... should have done this side 1st..the drivers side would have been much easier to match it..trying to match the straight side with a bunch of offset compound angles ain't easy..
So ive got it back to the mufflers now..

[mongocanfly]

Now for behind the mufflers...
I know I'm gonna run these pipes up higher, I want to get behind the axle,
So I'm thinking I will sweep both sides up and inward till they're about 6in apart..
They will run to the back brace and have turndowns on the end..
For the most part it will not be visible from outside..
Which is the way I wanted it..
The last pic shows kinda how itll end up..
And attached to the crossbrace..and turn down behind the bumper

That is really nice work on the exhaust. I like the look.

[regan wilson]

Looking good Greg.

[72 tigger]

Greg. now that is what is called a CUSTOM EXHAUST for sure. Very clean and neatly done.

[mongocanfly]

Thanks Gary..
Heres a sorta mock up of how it'll run
The turn down at the end will be cut off level the the bottom edge of the tube

Looks good

[Ol Blue K20]

Nice looking exhaust, nice work.

[mongocanfly]

Thanks Regan and Dale..!
Got the offset for the pipes mocked up...what a pain trying to make 2 offsets exactly the same..

[mongocanfly]

Well among trying to get a bunch other stuff done, I got some welding time..
I got the after muffler pipes 75% done..I say that because I'm gonna wait til I set the bed and bumper on to get my length and turndowns like I want them..but all these offset bends are done..!!
Moving on to hangers...
Yeah, that's alot of hangers...but its cheaper to buy in bulk...I'll use them somewhere
Im only gonna do 2 on each side...1 before the muffler and 1 at the cross brace near the rear turndown

[joedoh]

nice work greg!

[8man]

Seriously, I am going to have to send Laura's 48 to you for exhaust. That is pretty.

[mongocanfly]

Thanks Russ and Robert..!!..
I just started messing with tig a month or so back...just for the purpose of wanting a ss exhaust system.. I'm far far away from being any good at it.. getting more comfortable with it and getting a little better..but I doubt you'll ever see my welds in the tig hall of fame..haha
