I don't know if it's just my car, but my fuel injectors are very loud. I don't think they use to sound like this. They have sounded like this since i got my headers, cat,fp, and exhaust. Do you think that i might need to get larger fuel injecters. My car has about 60,000 miles on it and it's a 2000 zts. Also, which cams are the best: Crower stage 2, ford racing street/track, or are there a different kind that's better.
