My oldest son drives a 96 Toyota Rav4. As he was getting ready to return to college yesterday, I noticed that his car was louder then normal. After crawling underneath, I notice that the catalytic converter pipe was leaking and needs to be replaced. I took the car to Midas and they confirmed what I suspected. I was given an estimate for the catalytic converter and the rear muffler from $800-$1,000. OUCH. I did not have the work done. I looked up the parts and discovered that I can get everything for around $360. I have a variety of tools to tackle this job. I don't have a torch, but I have a saws-all, side grinder, dremel, etc. for cutting off the old stuff. The pipes are connected with flanges with gaskets and nuts an bolts. Is this too difficult to tackle?
