I had a low catayst pressure code set about a week ago, I had an earlier post. I one want to see if it sets hard again, and if it does I plan on pulling the cat and getting a new exhaust system put in, maybe a header if I can find a reasonable on. I haven't done enough research yet, just had the truck a month or so. If it doesn't comeback, then I will just leave it be for a while as the truck is running fine has decent pressure when you cover it with a gloved hand. I do not see any leaks present on a visual inspection. It may just be plugged up. I will see. It would help if I had a owners manual.(bank repot). I am waiting on one of those as well. I will see if I can find a copy of the pages somewhere on the web. btw forgive my spelling and grammar in this post and the previous one's working graves I tend to get loopy and careless at times. Thanks
