The present concepts relate to turbocharger exhaust arrangements. One example involves a system that includes an internal combustion engine configured with a turbocharger. The system also includes an exhaust arrangement comprising a post-turbocharger (PT) exhaust pipe connected to the turbocharger and positioned proximate to the internal combustion engine, the PT exhaust pipe extending away from the turbocharger along the internal combustion engine. The PT exhaust pipe includes a first portion extending above at least one part of a set of header exhaust pipes connecting the internal combustion engine with the turbocharger. The PT exhaust pipe also includes one or more additional connected and contiguous portions extending below at least one other part of the set of header exhaust pipes.

An RF window and a method of manufacture of the RF window are provided. The RF window of the invention has very low reflected RF power. The RF window includes a center sleeve assembly including a ceramic disc mounted within a copper sleeve. The ceramic disc has opposed surfaces, a ceramic surface coating is applied to each of the opposed surfaces. The ceramic surface coatings are selected for a particular application of the RF window. A pair of end assemblies is removably assembled with the center sleeve assembly. An end assembly mating face is arranged for adjustable slip fit engagement within the copper sleeve of the center sleeve assembly to define a respective cavity on opposed sides of the ceramic disc with the mating face positioned at an adjusted position. An intermediary ring is fixedly secured to the end assembly with the mating face at the adjusted position.

An attachment is provided for interchangeably converting a ski simulating machine into a rowing machine, the ski simulating machine having a frame, a pair of skis slidably mounted on the frame to move in forward and rearward directions on the frame and means mounted on the frame for providing resistance to the pair of skis during at least one of forward and rearward movement. The attachment includes a seat mounted for guided sliding movement with respect to the frame, foot support means mounted on the frame for bracing a user's feet when the user is sitting on the seat, and means for coupling the resistance providing means for application to a user's arm movement during a rowing exercise.
