I talk to a mechanic i know. According to him getting a cat back will make the engine rune lean and burn up my echaust valves. He recomends gettin a fuel pressure regualtor and uppin the flue pressure by 5psi. Is this a know thing? BTW, hes a good friend of mine and not tryin to sell me anything.

 

no you do not need a fpr just a catback, adding 5 psi of fuel pressure will hurt your engine mare than help, your o2 sensor will make any corrections if any are needed

 

He would be correct if the motor is carburated, but no Fpr is neded

Haha, I would never trust that mechanic

A header makes you run slightly lean. Nothing to worry about though. Just get it, period. How can you even ask somebody about the effects of a catback in your car? welcome to 1950.

 

i was just askin, im probably gona end up gettin a spoon axel back anyways so i dont think there will be a problem.

 

Yeah... your mechanic really doesn't know jack **** about how your motor works ....
