The popular RC40 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 standard bore centre exit. Front pipes come either "straight through" for use only with the rear muffler, or with a built-in resonator for quieter twin-box systems. All tail pipes are highly polished with rolled edges. Stainless steel front pipe direct to rear muffler available for single box system.
