i just got a 1991 celica gt w 130 k miles and i noticed that there is a whistling noise when i rev it up to high rpms i just tell people that its the turbo and some people believe it. im thinking that it is the muffler or a leak but im not sure if so what do you think about the sport compact flowmaster muffler.

The whistle is likely a crack in your intake system or a small hole in your exhaust. Visual inspection will tell you which. Also, for the intake system, you can look for leaks with a can of carb or intake cleaner. Spray the outside of the intake with it. If there is a crack and the cleaner makes it into the intake stream, the engine will stumble.

Flowmaster makes a pretty good product. Just choose the right size (probably 2.25" for your application).
