2.5 Inch Inlet/Outlet Universal High Flow Front Catalytic Converter Direct-Fit with O2 Port(EPA Compliant)

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!

I was a bit skeptical at first, but regardless I felt like giving this product a chance. I have a 1998 ford ranger 2.5l, and I knew my cat was clogged up causing it to stall once hot. I ordered this and some 2" piping and welded it in. I utilized the O2 bung and had it directed after the cat not prior, and put my O2 in it. Car is quiet as ever, there is a bit of a smell from it but I don't mind it. No codes either, I also want to mention that I ran a weld/bead across the edges of both sides of the heat shield, after reading some reviews I heard they fell apart, so I reinforced it.I will edit this review if something changes.

Good

Este sí cumplió mi propósito cómo silenciador

Exact as described and fit eat i needed them for perfectly. Great quality construction and made truck sound nice and deep

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.

I’ve bought these for three different vehicles two 2000 ford expedition 5.4l and a 1997 ford f150 4.6 l and they’ve always worked well and have a lot more low end torque. If you put them on right and new O2s definitely worth it.

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