Welding the factory cat to the header will not cause the cat to fail.
That's what I'm hoping to hear. Have you had success with doing this? I have read of people having issues with the stock cats failing after doing headers this way and ending up with detrimental affects when debris gets sucked back into the engine. have you heard of that happening?Welding the factory cat to the header will not cause the cat to fail.
Stock cats fail when they are already close to end of life.
Sparks automotive. In Santee, California welds up this deal all the time. So do some others. People who have done it are very happy. You will need a tune. Call Cajun.

Thanks for the advice. I just don't want to go through and have to run headers, high flow cats and antifoulers for the o2 sensors to not throw a code. plus add in uprev and it gets really pricy to do that.The best thing you can do is the shorties and high flow cats. I honestly dont think salvaging the stock cats to weld onto the new shorties is worth it. However, if your looking for the cheapest simplist fix, you gotta do what you gotta do. As far as the lean condition, every truck is different, and 99% of people who put headers on, either long or short tube, will require Uprev. But with the stock cats and shorties may be OK. I know it sounds complicated but it is very painless and worth it.

I am in Riverside, so actually right down the freeway from SB.Where in California are you located? There is a shop, FMS Performance in San Bernardino that will do the whole setup with new headers, cats and full documentation.
Just remember, the stock cats commonly fail and can cause engine failure in some situations. I don't think you need antifoulers for that setup.Thanks for the advice.

Ive read that a few times and that's my fear with stock cats. With high flow I wouldn't need to space the O2 sensor out of the stream to not get a code? Also to clarify with doing high flow I do have to do Uprev correctJust remember, the stock cats commonly fail and can cause engine failure in some situations. I don't think you need antifoulers for that setup.

As I understand it, it's the cracked manifolds that makes the cats overheat and fail.That's what I'm hoping to hear. Have you had success with doing this?

I was thinking that also. Just scared to take the plunge and risk the motor. The stock cats have a screen between them and the manifolds is that right?As I understand it, it's the cracked manifolds that makes the cats overheat and fail.
I don't know if there is one. Hopefully someone here on TT has info on that. However, as long as you have leak free headers and good O2 sensors, there shouldn't be anything messing up the cats. Well, unless they are hit by a rock or something. Just have the AFRs checked and preferably Uprev it.The stock cats have a screen between them and the manifolds is that right?
Will do! That type of customer service is hard to find these days, Thank you!!Give Jeff a call and he will explain everything to you. Even if you don't plan on buying anything from us. Cajun Bpipes | shreveport, LA 71129
