Five Stars: Excellent Build Quality and a Perfect Fix for the P0420 CodeIf you own a $2004$-$2008$ Acura TSX, you know how frustrating it is when the notorious P0420 code (Catalyst System Efficiency Below Threshold) pops up. After comparing prices for OEM parts, I decided to give this unit a shot, and I was genuinely impressed with the quality.The construction uses 409L stainless steel, which is significantly better than mild steel and should provide excellent longevity, especially when paired with the robust stainless steel welding. The laser-cut flanges were spot-on for a direct installation—it bolted right up to the existing manifold and mid-pipe without any bending or wrestling. They even included the gaskets and hardware, which saved me a trip to the parts store.Crucially, the unit uses a large-area honeycomb ceramic substrate (as shown in the diagram), which is key to achieving the necessary high efficiency. After the install, I cleared the code, and after several drive cycles, the Check Engine Light (CEL) has stayed off. My emissions monitors are running clean, and the car's engine note and responsiveness are back to normal. This is a solid, professional-grade solution that saved me hundreds over the dealership option.

This is an excellent, high-quality catalytic converter. It's made of good parts and weighs a ton. I appreciate the honeycomb ceramic substrates. Oddly, it didn't come in the box pictured in the product images. It came in a boring unmarked cardboard box. But it's still great.

This kit works extremely well as a direct‑fit replacement. The pipes line up cleanly, the welds look solid and the included hardware makes installation straightforward. Once mounted, the system seals tightly and the engine runs smoothly without any rattles or exhaust leaks. The build quality stands out. The materials feel durable, the bends are precise and the overall assembly has a sturdy feel that inspires confidence. The gasket and clamps fit properly, making the job easier for anyone doing their own repair. The value is excellent. Getting a complete converter kit with reliable fitment and quality components at this price makes it a smart buy for restoring proper exhaust performance. Overall, this converter kit delivers dependable construction, easy installation and great value. It’s a great choice for keeping your vehicle running clean and smooth.

When I am buying something important I read a lot of reviews and pay attention to to details . I didn’t want to spend a fortune buying Oem so aftermarket was my only other option. This PHILTOP CC is unbelievable in quality and an exact replica of the one I removed. It feels and looks like original quality and matches up perfectly . It came with all hardware and even a how to guide. For the price I am very pleased!

Fits perfect. Improved design at the flange so you don’t need an angled socket like the original.

Perfect fit on the engine side, on the muffler side you may need an adapter if your's is like mine where both pieces are flared out. Other than that it was and is a perfect fit. I fully stand behind this company and recommend purchasing from them.

Fits my car perfectly. After installing it, then after several engine shutdowns/starts, everything became normal.
