Some Technical Benefits of going with Fabspeed;
Construction
Hand Made - All Fabspeed systems hand built out of High Quality T304 stainless steel 16-gauge C.N.C. mandrel bent for optimum power.
Weld - Each TIG weld is hand finished internally, only butt-welded junctions are used, and flange openings are size matched to their ports, all to produce the smoothest flow possible.
Flanges - All Fabspeed flanges are produced utilizing Investment Casting, also known as lost wax process. The mold is made by making a pattern using wax or some other material that can be melted away. Parts made with investment castings often do not require any further machining, because of the close tolerances that can be achieved.
