The Extreme Online Store Up-Pipe has been made with beefy local raw materials. The flex joint is 321 Stainless Steel w/ an Interlocking Liner and tubing is a heavy-duty 14 Gauge 304 Stainless Steel that has been CNC Mandrel Bent and finished up with a nice brushed finish. Their flanges are made out of 1/2" 304 Stainless Steel and are fully machined on all sides. The insides of their flanges are "cut-back" to allow the pipe to rest inside the flange which gives you a nice flush mating surface thus allowing optimal flow through the pipe.
