Hey man, how did the cat work for you? What numbers did you put down with the cat and i/c piping? I wish I coulda stuck around to see yours...

I've had mine installed for about three months now. No catalyst efficiency CELs until just a few days ago, and now I'm finding that I'm getting an catalyst efficiency CEL after repeated high rpm runs. I cleard the first CEL, and a few days later when I got on the throttle again, I got another CEL. Seems that the Random Tech cat can't match the stock unit's efficiency. If you have seen the stock cat, that may surprise you because the stock cat has two catalyst bricks with the rear O2 sensor sitting in between. The first brick is quite short, and I wouldn't think that it offers much catalyst capacity.

Guys with the Random Tech HFC. DId you get any CEL light? Is the 02 cheater mod needed for the Random Tech unit?

I got the CEL once in a while with and with out the extender. It seems that the cat flows too much for the sensor and then with the extender it doesn't flow enough...Still a good cat though.

Yes, hard driving sets of the catalyst fault code (P0420).

Just wondering if any of you guys have gone from a test pip to a random tech. HFC noticed a big decrease in exhaust fume smells? B/C quite frankly, this is my only reason in getting one, and saving the environment some doesn't hurt either..hah.

I have the cheater and the only cel I throw is the p0300, and as far as exhaust fumes it seems about the same as stock to me (although I can't say compared to test pipe, never had one).

x2 - this is why I am reading this. With the nicer weather coming its annoying to run with the windows down sitting at a light when the wind shifts... Might as well be driving my bronco


you could almost put your nose in my tailpipe stock and not smell anything, so thats good!

No smelly fumes with the Random Tech HFC.
