The RV6 Catted Downpipe for the 16-21 Civic 2.0L 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.

When Honda first introduced the integrated exhaust manifold maybe people were upset that conventional “headers” were now obsolete. This is especially true since the K-Series platform produced some very impressive performance gains with quality headers. The components are stamped and welded with no consideration for turbulence or restrictions. This combined the 2 catalytic cores causes the engine to be literally choked out of a good amount of power.
