Project started October 2023,

 

Starting on the rear exhaust pipe we fabricated a temporary bracket to locate the muffler. This way we can lock in the position before making the bends to the head.


 
 
 
The pipe we had in stock was just slightly too big to fit in the head so Aad machined a tool to shrink the diameter using the press. We could have machined it but that would have left a very thin wall.
 

 
 
We cut off the front of the muffler and then manipulated both the muffler and the first bend untill the diameters matched exactly before welding. Muffler is exactly parallel to the lower frame rail and the bottom of the oiltank.

 
 
 
After finisheing the welds on the rear pipe we cleaned up and textured the stock fifth transmission mount. This will also be the mounting point for the front muffler, that is what the hole is for...
