Aloha All,

Hope everyone is doing well! I am in a little bit of a pickle at the moment. Mainly because this check engine light just stares me down every time i drive lol. However I'm not really noticing anything bothering my truck.... at least to the naked eye or while im driving or idled. I know that a Code 25 can mean many things and lots of people will say more than likely its probably an 02 Sensor. But i mainly have two questions.

• If there is a vacuum leak, like if its cracked. where do i find the replacement hoses? Does anyone have a resource where i could potentially buy a complete hose kit?
• If i wanted to install an after market headers and exhaust; like LCE for example. Does the current 02 sensors need to be present or can it be deleted?

Any advice helps!

Thank you
