99 K1500 Silverado 5.7, Need new Cats

dietz4ibanez · February 22, 2007

Well I have almost 200,000 miles on my truck and periodically my engine light comes on for catalyst efficiency bank 2. Well I have debated going to auto zone and spending the $70 bucks or whatever cutting out the old cat and welding in the new. If you think about that it sounds like a pain. So I think that I am better off replacing the whole piece! from the cats back the exhaust is new... I want more performance with whatever I buy but I am trying to stay away from bolting the stock cats once a year for State inspections.

Any Suggestions? I have been looking through jegs and summit but I think that they are over priced and I could find something for a better price with more performance!

I want to put the best that I can so let me know what you think!

Thanks -Economy Builder

I am going to have to hold off on the cats tomorrow. I think that my front end is going to need some work and it seems to be something with the CV joints. I am going to have it checked out tomorrow! I cant complain this truck has almost 200,000 miles and the only things that have been replaces is the starter, battery or two, heater/ac control unit and thats it... I think that it will ride alot better once its fixed so i cant wait!
