Ok I have a sound and this started when I put my long tube headers on. My "buddy" drove the car to Shawnee for me and I found out later he hit 140 in it messing around. Which I was ok cause the car was fine. So I didnt have the cash to buy my full exhaust so I ran open headers on it. Well as you know with open headers there are a lot of noises so I paid it no attention. But it's almost a grinding noise and it only does it when the car is in motion. So anyway today I finally for my full exhaust on. There's a separate thread about it. But anyway we got the exhaust on and started it, rev'd it and no exhaust leaks! Well I pulled out and rolled my windows down and that same noise was there. I immediately thought (exhaust leaks) so I turned around and said hay fix it ya know? And he said reverse and come back In on neutral so i did. He said is you break pads? I was like what? He said ate those cheap brak pads and I said ya! Cause I bought freaking cheap a$$ brak pads. He said that the metal in the cheap pads is grinding on the rotar! And I had my buddy reverse and come back in and ya it sound like it coming from the wheel. But it's only the passenger side. He said most likely when my buddy did 140 he proly braked hard and it got that pad down to a metal spot. Idk I'm gunna try and replace the pads. But I want your guys opinion on what you think it is? It's a very dominant Noise guys. Thanks!
