on my 93 with the 351 my cats are clogged bad to the point im am loosing so much power and experiencing backfire it has the 2 cat setup but between the 2 cats the is a elbow i cleaned the first cat out but the 2nd cat closest to the front i can't clean because of the elbow i live here in schuylkill county pa where the cat laws aren't strict so my question is can i cut off the first cat clean the 2nd cat out and just run the exhaust to the 2nd cat and only use 1 cat ?

 

Best bet is to replace them! if CAT laws are strict chances are if you do that, it will throw a code because there is no flow to that other scensor

 

if i can't afford to replace them what is the next best thing?
