Nothing at all to do with the muffer

PO455 EVAP Control System Leak Detected
(No Purge Flow or Large Leak)

Now you see the value to the parts store code thing

You will need a repair shop, that has an EVAP
Smoke Machine and Scanner, to find and repair
the EVAP System (Evaporative Emissions)

P0455 P0442 codes 2001 dodge ram 1500

P0442 Means you have a small leak in your EVAP system. P0455 is a large leak.
The EVAP system prevents gas vapors from entering the air .
This code can be set by a leak in the lines or a clogged charcoal canister.
Most common reason is If you did not put your gas cap on all the way.
Hope this helps

It should be located near the outlet in the rear exhaust manifold, ahead of the converter. The downstream sensor 2 is the one located behind the converter or sometimes in the rear of the converter body.

Exhaust leak

it can leaking at a number of places
it could be the exhaust manifold itself or the flange where the manifold and exhaust pipe meet or at any of the joints on the exhaust pipes. or it could even be in the actul pipe itself. if you are on a tight budget you could go and ask a shop for an estimate on what it would cost to have the leak many shops offer free estimates. sometimes the franchise shops will even fix it for free if it is a real quick fix. my wife had a flange put in for free at a shop because it only took the guy 10 min. to do it.
