The popular RC-40 exhaust system was updated to the millennium range for the year 2000. All retain the optimum size 1.75" tubing for maximum performance and efficiency, but we now offer a choice of tailpipe size and configuration. This is 2.25" large bore side exit. Front pipes come either "straight through" for use only with the rear exhaust, or with a built-in resonator for quieter twin-box systems. All tail pipes are highly polished with rolled edges and come with late type hangers (except centre exit). Stainless steel front pipe direct to rear exhaust available for single box system.
