Lower priced unit compared to Walker or Boral, but unit has been working fine for several months now. Came with long bolts instead of studs for mounting them. Didn't use them, used hardware store studs.

This PHILTOP catalytic converter kit is a practical option if you’re dealing with a check engine light or emissions issues on Subaru 2.5L models. It’s designed as a direct-fit replacement for vehicles like Forester, Outback, Impreza, and Legacy, so installation is generally straightforward without major modifications . Being EPA-compliant means it meets federal emissions standards (though it may not be legal in CARB states like California), which is important to check before buying. The construction is typically stainless steel with a ceramic substrate, built to handle heat and exhaust flow while helping reduce emissions and improve engine efficiency . Performance-wise, it does a good job for daily driving and restoring normal operation, though it’s not as long-lasting as premium OEM or high-end brands. Overall, it’s a cost-effective solution that works well if you need a reliable replacement without spending a lot.

This high flow catalytic converter kit was an excellent purchase. It fit perfectly to my Honda Civic 2001-2005 1.7L without the need for modifications. The O2 port fit without problem and the whole system was well sealed.Since I installed it, the car runs smoother and with better response. In addition, it complies with EPA standards, which gives peace of mind when passing inspections. The quality of the material looks solid and durable, ideal to replace the original without spending more.

I put this catalytic converter on my 2003 Civic EX—fit perfectly with no mods needed. Passed emissions, no CEL, and performance feels normal. Solid stainless build for the price. Only minus is unknown long-term durability, but so far, it’s a great budget option.

Easy to install took about 2 hours to remove old cross pipe and install new one couple of studs came out of the head no bid deal just make sure no aluminum is on the threads the studs for the mid pipe come with a squared end making it easy to install without a stud extractor tool. Now i will wait and see how long this replacement will last. You will need to replace your o2 sensors if you damage them otherwise you can reuse the ones from your old one.Installation:4/5Quality:3.5/5

Bought for 2010 SE Nissan Frontier. The front cats fit no problem, the rear cats easily attached to the front cats with the included bolts and gaskets, but the flanges on the back of the rear cats did not align with the rest of the exhaust. They were just a bit cattywompus (just not painted I the right direction).We cut the flange off the muffler section of the stock exhaust about 2" back, and attached it to these rear cats with the provided bolts/nuts, then we aligned (with tow straps and grit) the exhaust to the now installed front exhaust system and rewelded it (to the stock muffler pipe). Theses rear flanges were simply not pointed in the context direction, but it was easier to cut the stock exhaust (more room) then cut the PHILTOP cats.This was not a big deal to us (me and husband) because we had the knowledge and equipment, but if you do not have a welder you will end up returning the product or bringing it to the muffler shop for this last step.

I recently installed the PHILTOP Catalytic Converter Kit on my 2009 Chevrolet Cobalt, and I’m quite pleased with the results. The fit was perfect, and it was pretty straightforward to install—no major issues. I appreciate that it's EPA compliant, which gives me peace of mind regarding emissions.Since the installation, my car runs more smoothly and seems to have improved fuel efficiency. It’s nice not having to worry about any engine light triggering due to the old catalytic converter anymore. Overall, I would definitely recommend this kit if you're looking for a reliable and cost-effective replacement.
