2007 Toyota Tacoma - Can I leave off my heat shield?

My head shield also fell off…not even sure what it covers!! It’s not the exhaust it’s basically rat under the drivers seat ? But yes also wondering how big of a deal it would be to just leave off?

If it’s a bottom heat shield, it can be left off. Your vehicle’s high enough where you wont start any grass fires.

If it’s an upper heat shield, those prevent the carpet and the bottom of your shoes from melting.
