Gains with a excellent exhaust tone and not having to deal with smell of running catless. Introducing the RV6® Catted Downpipe for the 110th Gen Honda Civic equipped with a naturally aspirated 2.0 K20C2.

This downpipe replaces the highly restrictive O.E pre-cat with a free flowing contoured casting and high flow 300 cell cat. The entire assembly is made of high-quality 304 stainless steel and is TIG welded by our master welders in the USA.  

The RV6® Catted Downpipe was completely designed using Solidworks 3D modeling and our Romer CMM system for extremely precise measurements. The transition from engine to tube was designed using advance flow analysis for maximum flow characteristics. This transition was then made into a high-strength 304 stainless precision casting. This allows for a very durable product with optimize turbulence-free flow.
