my cat makes a bad noise at a certain rpm and i wanted to know if i could change it on my own or does is have to be welded? i have a 95 accord 4 door dx

 

are you looking to change to a "catback" exhaust or looking to change out the catalytic converter?

Also what is a bad noise? It could just be the heat shield rattling so I wouldnt go replacing a catalytic converter as they are pretty costly.

But to answer your question when it comes to replacing either one................it depends. Replacing either would be a pain without a lift but its not impossible. What might require a shop is getting them off as often the bolts are rusted on and cant be taken off by conventional means. You often need a torch to cut the bolts off.

 

o ok got ya. i have a catalytic converter and i was told by a mechanic that it was the catalytic converter that was rattling making an errrr noise when i get to about 1700 rpms.

 

Sounds like you'd better let a shop with a lift get at that for you...
