Buy discount Magnaflow 39004 Universal Catalytic Converter - CARB Compliant Very effective cat for HC and CO emissionsBy Wayne BengstonI had one of these installed with a 2" exhaust on my 1988.5 Suzuki Samurai. My Samurai blew 10 PPM HC and .01% CO which is very low. However, I barely passed NOx, but I believe that is due to my EGR system not functioning as well as it used to, due to the low back-pressure of the 2" exhaust.Update;My Samurai stopped idling a while back, which I figured was a cogged idle circuit. Turned out to be a bad ground that disabled the feed-back system for the carb and so the mixture went rich for a few thousand miles. That literally melted the inside of the cat, so I have another one coming today.If your engine is not running in good tune, make sure you fix that before replacing the cat, and make sure you take care of any tuning issues that arise, or you'll be replacing a cat way before it's time...0 of people found the following review helpful. » More Information about Magnaflow 39004 Universal Catalytic Converter - CARB Compliant.Thursday, June 23, 2011
