I already have high flow cats on my xr8, but they seem to be cloging up. I was planning to gut the insides. I known the dust is bad stuff, but are there any tricks that make this job easier. Also does this make it much louder. Thanks.
I don't think you have the right idea on this. The reason EFI is used is that the engine MUST run in a narrow fuel/air mixture range in order for the cats to work. If the mixture is too rich or lean the Cats cannot work. This is part of the reason cats don't work on diesels (current type cats anyhow - there are different types that do work, however other issues are holding them back).grantj said:Removing cats does not expose you to benzene, it can under certain circumstances increase pollution. Cats are there only if the EFI computer doesn't keep the air fuel mixture correct, which some times it can't. After the introduction of unleaded petrol in the USA, studies by the government and private researches found that benzene levels did not increase without cats.
Yes, but carbies became so complicated to meet the fuel mixture requirements (to make the cats work all the time) that they became too expensive and complex. That and the fact that emissions are much tighter now mean there is zero (?) cars available with carby now.AlbertM said:A car doesn't have to have EFI to have a cat, carb cars have 'em too.
Spot on. Huge penalty if you are caught. Not worth the risk or any possible gain IMOMartin said:
Also do you realise its a $10,000 fine if you get caught without Cats? If you cant afford a couple of hundred dollars for Cats then your surely not going to be able to afford a fine like that....

You mention Broom Stick Cats in your earlier post!! I take it this term relates to the pushing of a broom stick through the Cat to clear the centre. Is this what you mean??
The Cat I run on my ED IL6 is an Off the Shelf Hi-Flow Straight Through Cat its completely round in shape and is only about 10 inches long.... It costs $ 240.00.... It runs no additional internal piping....
