This twin-pack of PHILTOP 2.5″ high-flow catalytic converters installs easily—bolts right up without welding, and comes with O2 ports and heat shields. They feel well-built and EPA compliant, and I noticed smoother exhaust flow and better throttle response right away. Just be aware: some users reported early failures like broken bolts or cracked welds, so keep an eye on longevity. Still, great performance for the price.

They are perfect... Nice upgrade/replacement for my 2009 Ford Explorer 4x4. They fit just right and a very functional... my O2 Sensors screwed right into them. My Truck sounds and runs great now, and you can't beat the price!!I'm waiting for everything to cure and I will post a video later

These high-flow cats were a solid upgrade for my exhaust system. The build quality feels premium – solid welds, quality stainless, and O2 ports in the right place. Bolted right up and improved flow noticeably. Great deal for two units. Definitely recommend if you're doing a performance upgrade or replacement.
