As of last saturday, I am the proud new owner of an 07 Tacoma DC,TRDsport. I noticed on monday morning that there was an annoying rubbing/vibration sound coming from the front passengers side of the engine compartment. After doing a search here it seems that the noise could be coming from either the air intake where it goes into the inner fender or the y- pipe after the cats being loose.
I have checked both areas myself and found the springs and nuts on the exhaust to be very tight and soild. The air intake has some slight movement due to being rubber mounted but overall, it seems tight. I still think the sound is coming from the air intake area so my plan is to remove the air intake and see if the noise goes away. If it is the intake, what are you doing to eliminate the noise?
