Hand made with real U.S. 304 stainless and tig welded made in the USA. 3" dual X Pipes for exhaust.  16 gauge 304 stainless steel.  Made of 3" stainless steel and the ends are expanded so 3" OD piping slides into it for easy welding.  We made these where one end can be clamped if you like with a joint clamp.  The other end needs to be welded.  See pictures.  It is a work of art.  This would cost you more money to build yourself if you are capable and hours of labor.   Not the cheap 409 stainless ones you see that are made in China that are thin.  These are thick 16 gauge.  Made right here in Michigan with U.S. raw 304 Stainless steel.
