  • 2016 - 2021 Honda Civic 2.0L


The RV6® PCD Downpipe for the 2016+ 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. 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 the 2 catalytic cores causes the engine to be literally choked out of a good amount of power.

10’000+ km Honest Review (2017 FC2 6MT) FBO

I decided to run this dp on my car for a bit so I can give it an honest review, I have ran this rv6 catless downpipe for around 10,000 kms now and i'm honestly really impressed with it. The stock dp creates a massive restriction and literally chokes the car out, this dp open’s the car up immensely (Which is vital especially with an N/A car) and IMO it doesn't smell too bad really... The biggest change I saw was in the throttle response and the substantial torque increase, it's very noticeable... However I only recommend this dp only if you're running a full exhaust system because even if you upgrade the dp the rest of the stock exhaust is also a major restriction. The only gripe I have is that for the money they don’t include stainless hardware, so my exhaust studs rusted almost instantly up here in the north. I have this RV6 dp paired with a function works mid pipe and a custom fabbed Vibrant 3" 304 Stainless exhaust using their ultra quiet resonator & TVP muffler, after all my mods I can truly say this car feels like a true Honda now! Always a huge thanks to Humza and the team at unity, they’ve helped me turn this car into my “ultimate daily” hands down best & most professional customer service I’ve ever had.
