MIL light came on about an hour ago when I started my 05 Ram Hemi. VERY loud and power was sluggish, got home and flashed the code with my Superchips: P0143 Fuel 2/1 lean. Looked under my truck andf the Longtube header had completley disconnected from the Cat, just hanging there.lol 3 9/16 bolts and washers fixed that problem real quick

Goes to show that not all MIL fixes are under the hood or sensor related. Hope this may help someone in the future.

LMAO!

 

Guess we know why it was VERY loud, LOL... When I did my headers, didn't trust my ability to weld my cats back in while laying under the truck. Got a quote of just $75 for my local Meineke to just measure what I had left and tie the cats back in, then all I'd have to do is extend wires. I jumped on that deal!

Drove 6 miles down the highway with it open after the LT headers, right thru town and EVERY head turned in my direction, LMAO!!!

 

So am I reading this right that your welds broke? Ouch!

 

No, the 3 bolts from the clips had come off and the cat dropped down from the header.lol Hammer I bet that did sound nasty. Bolted both clamps up real nice.
