04CHASE Posted December 23, 2006 Report Share Posted December 23, 2006 well im working on getting the truck runnign and doing a few things. so i got the SS on the lift today because i needed to do a few things. i was in the process of removing my exhaust tto paint it to prevent rusting. and i get to the cats and pull them off, i look inside and see this and i thought well crap these didnt last very long, i had them on for about 1500-2000 miles, i think it was from a couple of runs that i made while running it excessivly rich. these are the supposed high flow maggie cats (59599) and i thought they would be able to handle a bit more than this. anyway im deceidign weather or not to replcae them or gut them right now. i know i have some more tuning to do so ill probably gut them for now and replace when i get everything dialed in. what a nice christmas present , santa killed my kittie's Quote Link to comment Share on other sites More sharing options...
Black2003SS Posted December 23, 2006 Report Share Posted December 23, 2006 Chase, How would diagnos that without pulling the cats? I have some nice KR showing up now and I suspect teh cats. My cats are a dark blue or, that dark oily discoloration. I dont recall them looking like that when I had them welded in. I think I might gut mine too.

04CHASE Posted December 23, 2006 Author Report Share Posted December 23, 2006 the only way to really diagnose is to check them , i got a cat code a while back but didnt think of it , i cleared it and it never came back . so i am glad i found this. im not really pissed it just kind of surprised me, im kind of scared to look anyfurther and see what else is wrong.

Black2003SS Posted December 23, 2006 Report Share Posted December 23, 2006 I keep getting a sensor 2 code every once in a while lately. Thought it was just a bad sensor. I better pull my cats asap. I might do it tomorrow. You can just knock that stuff out with a metal bar/hammer right? Should just fragment. Then I can have Zippy turn off my cat O2 sensors.

jaymoney Posted December 24, 2006 Report Share Posted December 24, 2006 Good thing you found it before there was a melt down. Quote Link to comment Share on other sites More sharing options...
BlackSS04 Posted December 24, 2006 Report Share Posted December 24, 2006 (edited) so the only way to know if your cats are going bad is to take em off and check it? and how long should I go before checking them because I got them on about a month ago. the magnaflow cat warrenty is for eighty thousand miles, so this is bs if they are going bad so early.

04CHASE Posted December 24, 2006 Author Report Share Posted December 24, 2006 well lik ei said a rich condition with a blower and higher egt could have caused thi s, i do know i was running pretty rich while doing dome tuning a while back but i thought they would be able to handle a little bit of rich ness. i guess i proved my self wrong. well the good sid eof this is they could have been clogeed when i was running at the track so when i gut them it should see more gains.

Vortec MAX Posted December 24, 2006 Report Share Posted December 24, 2006 well the good sid eof this is they could have been clogeed when i was running at the track so when i gut them it should see more gains. Looking at those things, I am surprised your truck even ran. There was a lot of restriction there. I would think you would see some SERIOUS gains if those were straight through. Hint Hint.
