hi guys. I have a 02 screw with the 4.6 engine. I was getting a cel coming on and a p0420 code. I read about it here and did the gotts mod and my light didnt come back on. I now have a rattle in my muffler but not the converter. I'm guessing its pieces of the converter inside the muffler. Anyone have a ctuaway picture of an oem muffler or know how to get those pieces out? i was thinking of just taking off the muffler and seeing if anything would come out. thanks in advance.

 

you'd be best to get the cat checked and at the same time have the shop look at it....

its a great time to get the exhaust upgraded....imo
