Magnaflow Catalytic Converters - 49 State Legal Reviews


BUY MAGNAFLOW-YOU WON'T BE DISAPPOINTED

Reviewed By Thomas R. F (MC Carr, KY) Reviewed for a 1998 GMC Sonoma —9/1/2009 5:00 AM

The old converter was loose inside and making a terrible sound. Magnaflow advertised that it was a direct replacement; no modifications. WELL IT IS! EXACT FIT! I ALSO INSTALLED A GIBSON EXHAUST: CAT BACK. I noticed that my engine runs slightly cooler, and at acceleration I can feel a difference(not neck snapping but it seems to run better). I was impressed with the quality and the workmanship, it is excellent. Time will really tell, but by the appearance of the converter it looks like it will out last the truck. A couple years back I had the converter replaced at a muffler shop and it hasn't lasted that long: the price was well over $150. LISTEN, IF YOU NEED A CAT BY ALL MEANS BUY THIS ONE, HONESTLY!

Eastern Catalytic

Reviewed By Paul D (Rialto, CA) Reviewed for a 1992 GMC C/K 2500 —8/24/2015 8:34 PM

This unit solved my issue in passing the California Smog Test... A 1992 5.7L is as clean as any new car today! (HC= 14/7, CO=0.03/0.02; NO=299/34) WOW! I should have replaced my old Catalytic Converter & O2 Sensor units first and stop worrying about the test results.

Good catalytic converters

Reviewed By Lowell L S (South San Francisco, CA) Reviewed for a 1994 Ford Mustang —2/9/2016 12:12 PM

They do their job. Only bad thing is having 4 converters quiets my Mustang by quite a bit.
