i hear you loud and clear on this one! I hear a noise when i am at higher speeds 50+ and in some cases at lower speeds and when i accelerate i get a low ticking noise right under my feet! i have it to the dealer, the mechanic, the muffler shop and no one can answer me this one! i was told i have ticking injectors ( which i do have) but there is no way they are as loud as the noise i am hearing!!!!
