I'm as lost as you on that one . It still worked , so to speak . I can tell by the different exhaust smell . Never stopped it from rattling .

The plenum is as clean as you could hope for . Wasn't rich IMO , not since I had it . Being parked in a garage , I'd know . I'm just chalking it up to Chrysler's bad cats . Not clogged , the catalyst comes loose in the shell , then starts deteriorating causing the rattles from being loose . In my case , it was probably blocking the exhaust at times . That's my take anyways . I'll know soon enough .

Never got for a ride yet but that's coming in an hour or 2 . Sure seems more responsive to the gas . Oh yeah , and sounds great with the Magnaflow I installed . I'll know if this was my issue or not and let you know tonight .

BTW , thanks for helping . Something you said clued me in on the cat .

 

The cat was definitely an issue . Not 100% , but 75% for sure . I think the other remaining issue is in the trans . Just gotta grab some oil and a filter to swap the governor pressure solenoid and switch . Do a band adjustment while in there and hopefully not have to go back in after that . Maybe Santa can get me a new B&M alum pan with a drain plug to make changes easier . I love 'em on my jeeps
