We're really excited to bring RV6 Performance on board! Seeing RV6's involvement in Honda's successful Team Honda Research Civic Si and Type R racecars provided an excellent testament to the durability of the products in extreme testing conditions. Furthermore, speaking with many existing customers of RV6 who all held positive product and customer support experiences with the brand assured us it'll be a right fit for Unity Performance and RV6 Performance to join forces!


This downpipe replaces the highly restrictive O.E precat/down with a free flowing contoured casting and 3.0"/2.5" tubing. The modular designs allows the 2.5" portion of the downpipe to be removed at the Vband connection and replaced 3" front/A pipe. We maintain all factory heat shield mounting points for thermal management. The entire assembly made of high quality 304 stainless steel and is TIG welded by our master welders in the USA.
