Carby Carby is a line that originated strictly as racing exhausts made using only hand workmanship. It is made of 100% stainless steel and carbon and features a cylindrical cross-section. The couplings among the different elements are checked accurately and optimized to achieve uniform gas flow. The assemblies are made with templates using manual TIG and MIG welding processes, whereas the bushings that couple the cylinder are made of solid machined metal. The Carby exhausts are available either as a muffler that can be adapted to the original manifold or as a complete kit. The mounting device can be selected in either the high- or low-position version. Improved performance can also be obtained simply by replacing only the end section, while also achieving a significant decrease in weight.
