I just finished installing the jba lt headers with matching jba catless h-pipe and now when i get around 1500 to 1800 rpm's it sounds like metal grinding right under the driver side floor pan. Like its literally under my feet or damn near close to it. I already checked the steering rack bolts, the starter, the steering knuckle, and i dont see the headers touching anything. The only thing that i can see is the hanger of the h-pipe is resting up against one of the bolts on the transmission crossmember. Dont know if that would cause that much noise but its the only thing i can find short of taking it to a mechanic and getting raped just for them to look it over. Also if you heard the sound clip of the jba lt headers and h-pipe on jba's website theyre full of ****. My car is so much louder than that, that i almost feel scared to floor for fear of getting pulled over. Well if anyone has any suggestions that i missed or had the same problem let me know. Also car doesnt pull at all so i dont think its the steering rack. thanks
