RV6 Performance 12-15 Civic SI Downpipe w/ High Flow Cat
Introducing the RV6 I4 Precat delete (PCD) for 2012 Civic Si and 2013+ Acura ILX equipped with the K24 engine. The RV6 I4 Precat delete replaces the highly restrictive O.E precat with a free flowing contoured casting and 2.5" tubing. 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.
RV6 has been manufacturing PCDs for the V6 Hondas for around 5 years now. Over that time, we have obtained much experience on how to make PCDs last. PCDs 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.

Nice easy install. Have a 15 si, running without flashpro at the moment but sounds great, not obnoxiously loud. Live in philadelphia, the undercoat dont think is needed, just had snow and put my car on the lift no signs of salt reaching it
