Great fit and solid performance for my 2012 Accord 3.5L I replaced the catalytic converter on my 2012 Honda Accord 3.5L with the PHILTOP High Flow Catalytic Converter (OE# 16643), and it was a straightforward success. It fit perfectly—bolted right up with no modifications needed, and the flanges and pipes lined up cleanly with the existing exhaust. Installation was relatively easy for a DIY job. Once installed, the check engine light stayed off, and the car runs smoother with noticeably better exhaust flow. Throttle response feels a bit sharper, and there’s less restriction compared to the old clogged unit. It’s also quieter than I expected for a high-flow design—no drone or excessive noise. It’s listed as EPA compliant and covers a wide range of Honda/Acura applications (08-16 Odyssey, 09-15 Pilot, 08-17 Accord 3.5L, 13-18 RDX, 09-14 TL, 10-15 MDX, etc.), which gave me confidence in the fitment. Build quality feels solid, welds look clean, and it seems well-made for the price. If you’re dealing with a failing cat on one of the compatible 3.5L (or 3.7L TL) Honda/Acura models, this PHILTOP unit is a reliable, direct-fit option that works as advertised. Highly recommended.
