RV6™ Modular Downpipe for 17+ Civic SI

Score: 5.00. Votes: 1

Introducing the RV6® Modular Downpipe for the 2017+ Civic SI equipped with the Turbocharged 1.5L (L15B7) engine. This downpipe replaces the highly restrictive O.E precat/down with a free flowing contoured casting and 3.0"/2.5" tubing. The modular designs allows the 2.5" portion of the downpipe to be removed at the Vband connection and replaced 3" front/A  pipe. We maintain all factory heat shield mounting points for thermal management. The entire assembly made of high quality 304 stainless steel and is TIG welded by our master welders in the USA.

Product Description

The RV6® Modular Civic downpipe was completely designed using Solidworks 3D modeling and our Romer CMM system for extremely precise measurements. The transition from turbo 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. 

On a turbocharged engine, we understand the importance of thermal management. This is especially important with the air intake path directly over the downpipe. That is why we designed this downpipe to maintain all factory heatshields.

    Honestly the best dp option for the CivicX Gen! The ability to use 3" to a 2.5" modular with vclamp front pipe or there soon to release full 3" RV6 Front Pipe is genius. This will then be a complete 3" dp/fp combo. The bonus is the reuse of the oem heatshield as well as the thermal protection of ceramic coating. Couldn't ask for a better product from a well respected company. Your dp and fp paired with my aFe exhaust for my 2017 Civic SI will make it roar!
