I own a 2011 ram 1500 5.7 Hemi dual exhaust pipes. Do anyone know if the catalytic converter(s) are welded on or clammed on? My truck is puttering when I take off and someone told me its the catalytic converter going bad. I have no check engine light on currently and its been doing this for about 3 months. Is this a serious problem? Will the truck ever cut off on me while in traffic? I want to replace it but I don't have the funds to do so right away. if anyone has or had similar issues feel free to chime in. Thanks y'all.
