My WRX page 

The sound you hear is a WOT drive by with the new exhaust. You first hear the approach, winding 1st gear from about 1/8 mile away, then 2nd gear as the car goes by and finally you hear shifting into 3rd gear and then backing off in 3rd gear. Excuse the final crashing sound, it happened when I stopped the recorder.

I've a MY02 Blaze Yellow WRX. I've had a number of sporty and high performance cars in the past, some of which I've modified a good bit. So far I'm very happy with my Rex and I'm going to go slow with the modifications. I've added a turbo timer and a F/A ratio meter.

The turbo timer is a Bogaard that I ordered from Australia. The F/A meter is also a kit I got from Australia. The kit was built by a friend, he is a great installer. I incorporated the lights into the dash next to the cup holder. The enclosure with the chip itself will be hidden under the dash. I've added a switch to turn it off and on should the flashing lights get on my nerves ;-)

The next big modification is the turbo back exhaust system, custom made for my car. I've added pictures and WAVs of the sound of stock vs. the new exhaust. The car sounds good! Not too loud inside the car but definitely noticeable from outside. It was a deep growl and seems to have markedly improved the spool-up of the turbo as well as extending the power curve a bit. You can now clearly hear the turbo through the exhaust!
