Yes it is "technically" possible to build your own downpipes from mandrel bends but it would take several bends (figure around $50 in bends) and would be very messy and easy to screw up (uneven inside!)

Also you would need to weld on spherical flanges to be able to mount them to the manifolds/headers.




Actually the manifold pipes are quite, quite easy to build. I had a local shop stub out two pipes for me with 45 degree flanges pressed into them. Cost all of two bucks. Then, I used a 90 and two 45's to make the front one. The rear one, I used a 90 cut off just a touch early... I could have used a custom bend from West Coast bending in retrospect... about a 75 degree bend or so is needed. Welded an O2 bung (another buck) to the rear pipe after I was done tacking it in place. Took an entire afternoon to finish the rest of the system. Total cost was under $300 for the entire system in 2" piping, including cheap mufflers.

The hangers are easy as pie. Get a cold rolled 3/8" steel rod from Home Depot or the like and bend your own hangers after tacking the pipes in place.
