my random technologies cat went bad about 3 weeks ago, but don't have the money right now (college student) to throw around about $70-$80 to put my stock one back on, return the random cat at my expense, then get my new random cat (as no charge of course), and install the new cat. i was wondering if im losing anything by doing this?? is it bad for any part of my car...or am i losing any power?? from what I know, i think i'll be fine as long as i don't have my inspection comin anytime soon. but thought i'd ask some of the more mechanically inclined to help me out with this. thanks in advance.

Bad Cat.

If your Cat went bad, it did so for a reason. I suspect you have engine problems. Check out our web address, there is a section that deals with why Cats go bad. We have sold several that peopple want to return but are unable to, becuase the engine wrecked them. They should last a LONG time. If your new Random Tech cat went bad, correct the problem before trying a new cat or you will probably wreck the new one as well.WarpSpeedPerformance.com

What, Daniel B. Martin doesn't know what reversion into the intake is? Oh my, what is this world coming to. Everyone knows what that is

Re: Please elaborate

When the catalytic gets bad enuf it starts to collapse causing a restriction in the exhaust system... This in turn allows blow back from the combustion camber back into the intake system where you'll start to see carbon build up in the intake manifold or even further upstream if it's bad enough.

Have you gone through any deep puddles??

I had a cat go out on me because I went trough a deep puddle of water. If you haven't gone through any deep puddles then you might have some engine trouble.

I think you had some bad luck there... I would think it wouldn't be typical of the catalyst block to separate from the wall just by going thru a puddle...

That's not reversion, though. That's just plain 'ol backpressure. Reversion is on turbo vehicles - when the throttle plates are closed, the pressurized air hits the throttle plates and reverberates back towards the turbine housing/compressor wheel if it is not vented out or recirculated through the system.. hence blow off valves or recirculation valves.

I thought it was whenever you have 'backflow' (like the Chikaru header ads) but I STAND CORRECTED...hehe
