Inconel FTW! Was originally expecting 3 setups to be mandrel bent, since thats what we estimated from the usual length of tube,but due to the piece of tubing being that was delivered being an extra long piece, I know have 5 
Downpipe material is 3"x.049" 321 stainless, bender had enough to make five downpipes so he made five 2 1/8" x .049" inconel 625 uppipes. Tubing weighs about 5 lbs or so lighter than a comparable 16g/.065" wall thickness setup, but is much MUCH stronger :biggrin1W

So here is a quick pic, obviously mil spec 321 stainless on the right and inconel 625 on the left. The 321 was also very expensive...usually 2"x.065" 321 costs me around $20 a ft, but this stuff is 2 1/8"x.065" and costs $60 a ft. The 2 1/8" being an odd ball size and usually found in .049" due to it being mainly for aerospace use and thinner wall sizes are more popular. Took about 2 weeks of calling around for it and finally had some shipped in from florida.
Really nothing that special to look at, could easily get mixed up with some stainless and not even know it til you tried to weld it. This stuff is very different welding wise compared to stainless. Luckily I have some 625 filler rod from my last job welding aircraft exhausts because that stuff costs about $60 a pound.

Picked up a stack of mandrel bent downpipes today, filled my entire back seat. 12-304/.065" and 5-321/.049" downpipes. The thin wall 321 dp has a noticable weight savings from the 304 setup. the 321 dp is the grey/dull setup and the one on the floor is the 304. same layout just different material and wall thickness.
