Installed this PHILTOP catalytic converter kit on a Subaru 2.5L and the fitment was spot on. Everything lined up exactly like the factory unit, which made the installation straightforward without any modifications. The build quality looks solid with clean welds and durable materials.After installing it, the check engine light cleared and the vehicle is running smoother with improved throttle response. The kit being EPA compliant also gave me confidence that it meets proper standards. It is a great value compared to dealership pricing and comes with everything needed for a proper replacement.If you need a reliable replacement catalytic converter for the compatible Subaru models, this kit does the job well. Great quality, perfect fit, and it solved the issue immediately. Highly recommended.

Okay, if I were looking for a catalytic converter for my Elantra, Soul, Tucson, or Forte here in Charlotte and wanted to keep things EPA-compliant without breaking the bank, I'd come across the PHILTOP 16646. They say it's a direct fit with a durable stainless steel body and all the hardware, which sounds pretty good for the price. The catch, as of May 2025, is that there aren't a ton of specific reviews out there for this exact PHILTOP model. Some folks with similar PHILTOP parts on these cars have had good luck, maybe with minor tweaks needed for a perfect fit, while others offer less feedback. So, while it's a budget-friendly option that should legally work fine for our emissions standards here in NC, I'd go in knowing it's a bit more of an unknown in terms of long-term performance and perfect bolt-on ease compared to a more established, pricier brand.

I got this because I needed to get rid of a P0420 code for the absolute lowest cost, and this fit and functioned perfectly. I would've liked to see a heat shield, but the other can be transferred or not used, it doesn't make a huge difference. All of the welds are seamless and well done, and all the cuts are very precise. The flanges are square and gave me no issues sealing up.
