Those cats with the O2 bungs are ceramic element though, not metallic. They do sell metallic cats for a lot cheaper than the Magnaflow's they're knocking off...

?? Yes, I got the high flow ceramic ones. But you're info about the price is incorrect. Mine cost much less than the metallic ones, by about $20 some dollars each.

 

I know that they're cheaper. But the metallic cats have a higher flow rate and will last longer than the ceramic element cats.

 

I like the Idea of the cats you guys are talking about. I think I will check and see if they make the metalics with the o2 bung. What about the rest of the y pipe? Do you think there is enough room to weld these cats in a ory y pipe? Or from the cats back will a custom pipe need to be made. I dont like the fact that a exhaust shop will have to make something from scratch ( you never know what you will get) and it wont be mandrel bent.

 

Hey guys i dont have AIR or EGR on my 00 pickup but the AEM headers i ordered have the fittings and instead of using block off plates i'm going to use freeze plugs. just a tip for anyone who cant find plates.

 

have you guys thought of puting a 3" high flow cat AFTER the y and extend the one o2 for the left pipe? I think I will just put in a pipe to interchange for inspection time. Anyone know if getting the rear o2's tuned out will effect the inspection machines in texas?

 

I believe that in texas you can 2 "not readies" and still pass when they check the codes and system checks. I am not sure how many "Not Readies" deleting the cats makes.

 

would it throw one for each heater and sensor or just the sensor or just the heater?

 

did you tune yours out with efi live? did you get your y fabbed up?
