Single exhaust?
 

You know how the efini 3 rx7 came in as a single exuast and was featured as the fc in the Initial d series, I was wondering if it was possible to mate two different exhaust companies togather to create a low tone yet powerful single exuast.. so, does anyone know if the racing beat downpipe can mate to the re Amemiya single exhaust intended for the Fd3s I own Fc
