i have a moded 350 that i just put in my car with heedman headers and an exhaust cut out, will the loud exhaust even with the cut out closed cause the knock sensor to have faulty readings, my one friend had a moded camaro to similar to mine and said that he had that problem?
is there away to fix that?

 

thread tape will help, also i think you can add a resister in line

 

yeah i think thats what he said to do how do u do that?
and what kind of resistor? i dont no much about electrical
