Question: Is it safe?
Answer: No.

Do people still do it? Yes. But, usually not for long.

BTW, that header is REALLY hurting you. It's the worst design for a header ever created. Really.

 

you can do it but make sure your car is tuned right after u install them i have a friend with a similar setup. ull be ok with 91 gas. bump up the fuel
