What's up gang, my car has had an intermittent TOB whistle that is hardly audible (most people think I'm crazy) since a month after I got it 3 years ago. All started when I drove it on a cruise/canyon run when I barely had 3 weeks ever of driving manual. I'm sure that had something to do with it, because while on the cruise it started to howl really loud but then quieted off back in town. It slightly whistles and not all the time, and not every day. I know its that because when I clutch in the sound is immediately gone. Its holding me back on getting Long tubes because I don't want to deal with dropping the transmission after headers are in even if people are saying you can still drop the trans with certain headers. And that's true, but what they are not saying is that you have to most of the time, use a strap to pull the passenger side header away, dent them, or loosen it. I don't want to spend that much money to do both at the same time. Headers are being done at a shop for a super cheap price. How long do I have before the whistle gets crazy annoying? Generally speaking.
