Another great experience purchasing from Two Step Performance. The catted down pipe will wake up your car, sound and performance. You aren’t going to feel the hp or tq, but car seems to breath is the best way I can explain it.

Fitment is better than OEM, fits like a glove.

The quality of the product is top notch, you will not be disappointed. Welds look perfect! Does not feel cheap or flimsy, very solid piece.

Install is easy if you have a lift, but it can be done on jack stands. I did the install without removing the Turbo Inlet pipe. Once the car has cooled down make sure to soak the down pipe bolts and nuts with Wd-40, several times.

I’d buy the Rv6 catted down-pipe again and I’d recommend it to anyone with a 10th gen civic.

Introducing the RV6 Modular Downpipe for the 2016+ Civic 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 the upper 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 1.5T 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.
