The customer has requested electric cutouts. So I built the exhaust in 2.5" straight back to the cutouts and the cutouts are themselves 2.5". From there back I built everything in 2.25". We have also converted the transmission to a later generation Tremec and applied a special crossmember to allow for this. It is because of this crossmember that I am able to build this exhaust so straight and without any bends before the cutouts..
