Yes , manifold shield. To check converter per Hoodlatch, just go under with cold cat and hit it , if loose innards it will rattle.

I cut the cat out and put a straight pipe in it when i bought the truck but last night i took the down pipe loose and replaced the donut gasket and put alot of high temp. silicon on it and so far its not rattling anymore so i think its fixed...Thanks for all the help guys

No cat, how do you keep the check engine light from being on all the time.

When i cut the cat out i took the o2 sensior out of the cat and welded it back into the exhaust so it still reads as it being there

Can't be reading right with no cat, should put check engine light on if in fact the check light does work.

NO the check engine light works because when it was missing on one cyl. it came on after i cut the cat out it just runs a little bit fatter now

Well the post cat sensor sends information to the PCM on how well the cat
efficiency is performing . No cat, poor performance, light on. Well who am I to say your light is on.
BTW you can buy a sensor to plug into the 02 sensor and the PCM still thinks there is a cat installed. I would never do it though.

I will just leave it alone it doesn't turn the check engine light on and it still runs great no problems i acutally think it running a little bit fatter helps it in the long run
