Message:
My check engine light has been on for a couple of months. I previously checked the code and it was a po442 (medium evap leak) and a changed the gas cap but that didn't help. I let it go and happened to check the code again yesterday and now it is a po455 (large evap leak). Two questions 1) Is it something to be concerned about or can I let it go? 2) Where is the charcoal canister so I can check the hoses? It is a 2002 quad cab 4wd 4.7 5spd. Oh, also my exhaust smells nasty so I assume it is the cat. Also I went under the truck and the cat was supper hot compared to the rest of the exhaust. Is there a aftermarket cat I can get that will increase flow and not cost a ton. I have a flowmaster super 40 on the truck and I don't want to make it any quieter if anything I want it louder (if the can has any effect on noise). Thanks

charcoal canister should be right in front of the fuel tank. also check the hoses at the evap purge solenoid under the hood.

nomar5, you can get a high flow cat, almost all of the auto parts stores can get you one. I think summit, and jeggs can get you one if the local parts stores don't have or can't get you one.
Good Luck

To find your EVAP leak, get under the truck and trace every line that comes off the gas tank. You'll find one eventually that is either cracked or has fallen off, it'll be pretty obvious. Replace/reattach it and clear the code.
And what exactly does your exhaust smell like? Is it affected by engine temp or how long it has been sitting?
And also, high flow cats are ridiculously expensive for basically nonexistent power gains.
