2.25 Inch 2.25" Inlet/Outlet Catalytic Converter Universal High Flow Front Cat Convertor Direct-Fit with O2 Port & Heat Shield(EPA Compliant)

I put these on my 2007 mustang gt and gave been running them for around a year now and they work amazing. My car is tuned, so these cats can take some heat and fuel but has only thrown a cat code 1 time in the time I've owned them.

I bought a 1999 Pontiac Firebird Trans Am (26 years old currently). I had the check engine light on. After diagnosis, it seemed the O2 sensor had to be replaced. Code was cleared, but came back on. The mechanic told me he thought I would additionally need to change the catalytic converter out. This is a great deal for TWO high flow converters. I brought these to my exhaust guy and he installed them for me. I cleared the check engine code AGAIN. It has not come back on since, and it has been a couple of month now. I highly recommend!

Easy to install, fit perfectly and sounds great. Really lets the truck breath when I step on the gas. Older truck, so no O2 sensor, but does have the port for one.

My pre obd2 truck passed the gas sniffer test just fine with this. However, please be aware that some states require proof of epa compliance. This doesn’t come with a certificate or documentation. So if you live in a state that requires that ( like Utah) you won’t pass the visual part of emissions.

Fit great. Passed emissions.

I was skeptical of this cheap cat at first but it seems to clean up the exhaust smell like any other catalyst.Granted I’m in Nebraska where they don’t do emissions tests but you’ll need to do your own research if you’re looking to find a compliant catalyst.Edit* it is now two years later, and I had to remove the catalytic converter with piping to do some unrelated repairs in the area and discovered the catalyst has completely disintegrated and is nowhere to be found, not even in the muffler or piping.My guess is that it was a super low quality catalyst and simply burnt up over 2 years.I became suspicious when I started smelling regular exhaust gases instead of the catalytic converter “clean smell”, my engine has always ran great and I do not abuse it along with religious maintenance and inspections, I firmly believe this was not engine related catalyst damage and I never had any misfires.I suppose the old saying is true, you get what you pay for….Next time I will purchase a Magnaflow catalyst, I have one of those on my Mustang for over 4 years now and it still works great, it was $200 through Stinger Performance, same size and shape as this cheap catalyst.

Its verh nice and good price it solve my problems thanks.

Didn't work to my Nissan versa. The car computer didn't erase the code. Maybe need an extra one.
