Re: 1972 C20 -Airride conversion-

Next up...

Exhaust

A lot of work, but it's fun work.

I went with 2 1/4" pipe, all v-band clamps and Trush welded mufflers.
mainly because I all had these from my year old exhaust.
That's also why there are parts already painted black, and new parts.


Started from the headers. on the drivers side. i Looped underneath the shifter assembly.
(not the greathes pictures but you'll get the idea.




Than an exhaust flexi, and straight back true the carrier bearring crossmember.
Passenger side was the same, but with an easy down and straight back.

After the crossmember it goes down and in, to go past the airtanks and next to the driveshaft.


Than back up, and real close to the frame, to avoid the panhard bar mount. and down past the shock.



The other side has the same idea. up and over the panhart bar mount, over the axle, underneath the shock mount tube, and back up over the brakeline.




I needed some more clamps, and bends to finish up so i took it all apart and finish welded it.
pile of pipes to weld:


I solid mounted the pieces over the axle, because there is not much room for movement. Did that with tabs like this.


mounted it to the carrier bearring crossmember aswell, used damping bushings for these:


Added extra flexies before the solid mounted part. to maybe get rid of vibrations.


Than it needed an H-pipe.
So up and over the driveshaft looked like a good place for it.
Went with a smaller diameter tube, for clearance purposes
offcourse there needed to be a clamp aswell.



So after plasma cutting the holes I tacked it in.


In the meantime parts came in. So back to the rear.
After the solid over axle part, I added a v-band clamp straight into another flexi.


than down under the frame, and back up into the mufflers.
I reused the trush mufflers I used in my old exhaust.
Mounted them with rubber vibrating dampers tot the frame.




Same for the other side.


And added a 90 degree out of the muffler, down to the side.

result... good looking, functional exhaust.



Next up, paint.
taped up the stainless v-band clamps, flexies and the stainless endtubes out of the muffler.


Than a fresh coat of heat resistant black


Endresult...



Wrapped up some parts. protection where the airhose goes over the frame, and the solid mounted parts, because they are really close to the frame.


All back in the truck.



I'm really happy with the finished result.
