RV6 I4 Precat Delete (PCD) for 2012 Civic Si and 2013+ Acura ILX with K24 Engine

Upgrade your 2012 Civic Si or 2013+ Acura ILX with the state-of-the-art RV6 I4 Precat Delete (PCD) specifically designed for the K24 engine. Witness a transformative shift in your vehicle's performance by replacing the stock restrictive O.E precat with the RV6's ingeniously crafted free-flowing contour casting and 2.5" tubing. Committed to excellence, this assembly boasts of high-grade 304 stainless steel, meticulously TIG welded by our experienced master welders.

Why RV6 I4 PCD?

Upon the K24Z3's launch, enthusiasts felt a void with the integrated exhaust manifold, as traditional headers became redundant. This sentiment stems from the significant performance boost the K-Series platform garnered through top-tier headers. A glimpse at the O.E precat reveals its economical design optimized for mass production, with apparent oversight for potential turbulence or blockages. Paired with dual catalytic converters, it inevitably curtails the engine's power potential.

However, RV6's legacy with PCDs for V6 Hondas spans half a decade, enriching us with unparalleled expertise in PCD longevity. Unlike regular headers dispersing stress across multiple runners, PCDs undergo intense temperatures and consistent engine-induced stresses, focusing on a singular region.

Features

  • Flange Sections: Cast using high-quality 304 Stainless steel.
  • Tubing: Durable 304 Stainless steel 2.5" tubing.
  • Welding: Precision TIG welded for superior strength.
  • Gas: Argon back gassed, ensuring the purest welds.
  • Includes: all essential hardware for a hassle-free installation.
  • Warranty: Rest assured with RV6's warranty, covering castings and welding for an impressive 24 months.

Dive into a new realm of power and efficiency with the RV6 I4 Precat Delete. Equip your vehicle with the best, and let your engine breathe the way it was meant to!

Good downpipe
J7cars | October 9th, 2025
Tested it on the dyno, lost significant torque as compared to a catless one, only issue is that it rattles when it heats up, besides that sounds great and is quite literally the best option for 9th gen civics.
