March 4, 2010 - Now that the driveshaft is done - at least, my part of it is - it's time to take on the exhaust.
This has to pass through a frame crossmember in order to get from front to back, and I realized it would package better if it did so at a 45 degree angle. I picked up some pipe with an ID a bit bigger than the exhaust OD. It's some sort of massive gas pipe, and my poor chop saw had a heck of a time with it!
I sectioned my 45 degree piece to match it to the thickness of the crossmember. To make things interesting, the crossmember tapers in height as it heads towards the sill. So the pipe insert had to be different heights at each corner. Careful measuring, and voila. Ready to weld in once I've cut out the crossmember.
On further reflection, I'm thinking this might actually be best if I leave the pipe as a round pipe. That'll retain more strength (not sure if it's needed here, but still) and will make the lowest point of the car a piece of very burly pipe instead of a thin exhaust pipe. It'll still have approximately 4" of ground clearance, but it's at the breakover point. We'll see, I can always weld this bit back together. And yes, I have considered how I'll remove the exhaust without cutting it up!
