Introducing the RV6® I4 Performance Bellmouth Downpipe Kit for the 2012-2015 Civic Si and 2013-2015 Acura ILX equipped with the K24 engine. The entire assembly is made of high quality 304 stainless steel and a TIG welded by our master welders.
When the K24Z3 was first introduced, many people were disappointed with the integrated exhaust manifold that made conventional "headers" obsolete. This is especially true since the K-Series platform 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.
