Fast2500Ak Posted November 26, 2007 Report Share Posted November 26, 2007 It sounds like a horrible idea, and probably is, but I have a friend whose done it multiple times and the engine miraculously seems to survive, he puts the truck up on a hill and pours oil down the tailpipes while running, takes it out on the highway and they explode inside or something and afterward the cats no longer seem to pose a restriction. Just wondering how filling the cats with oil kills the them and not the engine because it has to be inducing cat failure and collapsing them. I don't know, it just seemed intersting. Anyone else ever heard of this? Just curious. Quote Link to comment Share on other sites More sharing options...
usabodyguard Posted November 26, 2007 Report Share Posted November 26, 2007 and you are considering this with a SS? wow... just cut them off and turn them in for $$ precious metal cores... Quote Link to comment Share on other sites More sharing options...
detjoe Posted November 26, 2007 Report Share Posted November 26, 2007 dude if you do this to a SSS, I will need your address to confiscate it back from you. you can unbolt them, if you melt them using oil, where do you think the core is going??? its still in there. Please dont do this. see the post about the guy w/audi doing a port and polish... Quote Link to comment Share on other sites More sharing options...

Fast2500Ak Posted November 26, 2007 Author Report Share Posted November 26, 2007 I was just curious, no this is not something that I would ever do to my truck, I was just wondering if it actually worked. It did on my friends truck but it was an early 90's chevy with a single cat. It just seemed like a funny redneck way of gutting them. According to him the ceramic material just shatters and gets thrown out the tailpipes, come to think of it do they even use ceramic any more?

PladdPezzPunk Posted November 26, 2007 Report Share Posted November 26, 2007 (edited) the actual reaction is the oil boils and melts the substrate. the substrate allows NO exhaust flow, (damaging the exhaust valves more than likly) then the cylinder pressure driving on the highway shatters the substrate which flys out the tail pipe. Glycol antifreeze will do the same thing. If you want a quicker reaction, do it with gasoline. Either way you look at it, its a horrible idea, you run the risk of damaging your engine and creating a huge fire ball. all this means no more truck. good luck man Edited November 26, 2007 by PladdPezzPunk (see edit history) Quote Link to comment Share on other sites More sharing options...
dcairns Posted November 27, 2007 Report Share Posted November 27, 2007 Why gut the cats in the first place? They are not the huge restriction you may think they are. There are plenty of other mods that will get you more HP to the ground. Quote Link to comment Share on other sites More sharing options...

evandostert Posted November 27, 2007 Report Share Posted November 27, 2007 No you need to add a couple of gallons of gas into your exhaust and plug the tail pipe with a banana. That should work out for ya. Quote Link to comment Share on other sites More sharing options...
Fast2500Ak Posted November 27, 2007 Author Report Share Posted November 27, 2007 Is your friend the inventor of Direct Exhaust Injection (DEI)? Mike lol actualy, I've never seen him do anything to his engine that hasn't worked no matter how crazy or dangerous. He's either a genius, or really really lucky. But still, don't judge someone until you driven a mile in their truck, that way when you judge them you're a mile away and you have thier truck.
