Open Header

[Cwish]

I unbolted my cat and wanted to seed how it sounded so now it just goes out of the engine and where the cat was it is dumped. Will this hurt my engine im not hard on my jeep but i really like the open header sound

It wont hurt it. May throw a check engine light on and run a little rich. Might want to put a little turn down pipe on there though so the exhaust doesnt get anything too hot under there.
