I have a 02 Dodge Durango 4.7 4×4 and I have 3 cats which I've been told my best bet is to cut them off and run straight pipe do away with cats completely. I had to park it cause it spitting n spurting bad and wouldn't stay running so I was told to it was my cam sensor then $400 replaced then. Did that then still ran rough so I was told to remove cats. What's y'all thinking??
