MagnaFlow Universal Catalytic Converter Standard Grade Federal/EPA Compliant 94009 - Stainless Steel 3in Inlet/Outlet Diameter, 16in Overall Length, No O2 Sensor - Standard Grade Replacement

Replaced the catalytic converter on my truck and it runs better.

Good shape when it arrives and a good quality made product and works well.

I think these are very well built for what I was expecting. Although I haven't installed them yet but will be putting them on this week. I don't need them where I live but my truck sounds much better with them on. I will update more later. 5 stars so far. Update. They are now on my truck and the sound is amazing and power is back to normal. No exhaust popping without back pressure. Great cats.

great price

My 1998 truck was running hot on the highway for months. Couldn't figure out the problem, until it started running really bad. After 20+ years the cats were fouled and clogged. Took these down to my local muffler shop, and they put them on for me. No more running hot, and my fuel mileage improved a little too. Be certain about the size of your exhaust pipe before you order them, and try to match the length as closely as possible. You can go to Magnaflow's website to get specs and part numbers, then search Amazon for the cat with the part number you need.
