I have my exhaust installed. It went very well, I used a Summit 2.25" dual system that I got on sale for $135.00. It installed and cleared everything easy. I used 2.25" mandrel bent tubing to construct the pipes from the Langdon's split headers to the Summit exhaust pipes. A lot of cutting, fitting and welding, but a good result.
