I think you'll be ok, but you might unplug the ECU module before you have the front cooler welded. At least make sure they ground directly to the cooler.
I don't have a problem with any noise from the drivers and track, but I do have a k&n intake and a free flowing exhaust to drown out any other noisestoyota4runner said:Anyone else have problems with the wahl bros being noisy or is this not common? The wahl's are almost half the price but I dont want to have to do this twice. I'm running an intense track, not boosted and I'm gonna stick with 9T
