  • Regular price $329

Introducing the RV6® Bellmouth Downpipe for the 2015+ FIT (GK5) quipped with the L15 engine. This downpipe replaces the highly restrictive O.E precat with a free flowing contoured casting and 2.25" tubing. The entire assembly is made of high quality 304 stainless steel and a TIG welded by our master welders in the USA.


When the integrated exhaust manifolds was first introduced, many people were disappointed that conventional "headers" obsolete. This is especially true since Honda platforms produced some very impressive performance gains with quality headers. When you look at the O.E precat, you can easily tell it was designed to be made cheaply and mass produced. The components are stamped and welded with no consideration for turbulence or restrictions. This, combined with 2 catalytic converters, causes the engine to be literally choked out of a good amount of power.
RV6® has been manufacturing integrated header performance exhaust around 10 years now. Over that time, we have obtained much experience on how to make these parts last. Integrated header exhaust parts are subjected to high temperatures and constant stresses from the twisting of the engine which are unlike conventional headers that distribute the stresses between several runners all of the stresses are concentrated on one area.
