RC-40 exhaust system was updated to the Millennium range in 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. In addition, they now have stainless steel pipes for better appearance and rust resistance. 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. This stainless steel front pipe fits direct to the RC40 Millennium range of rear silencers/mufflers for single box system when fitted with freeflow manifold.
