I'm going to change my exhaust to run out the back of the car. I'm thinking about putting the spark plugs 5 inches from the end of the exhaust and the injection will be about 5 inches behind the plugs.

Maybe the father back I have the injection the safer I will be? I have an extra 10psi fuel pump and 100psi fuel pump collecting dust. I'm not to sure how much psi the nos solenoid can handle tho.
