Check engine light comes on, I go to a mechanic and they say that P0450Evaporative Emission System Pressure Sensor/switch. What does that mean? How do I fix it?

And I want to take off the stock muffler to make it a straight pipe with resonator. Does anybody know if I can, if it actually sounds good, and any positive performance outcomes?

Not sure if you ever got a resolution for this issue but exactly the same thing happened to me this weekend so I have an interest. Same OBDII error code but precious little in fo out there about this. I know enough that the only exact way to know with certainty what is causing the CEL is to take it to either an indy with SDS or a dealer. I can do that pretty easily but I'd like to go in with an idea of how big the universe is, i.e. we talking a $20 part or a couple of them in series or are we talking a different order of magnitude, e.g $2k part. Thanks.

Tried already the fuel cap.
