I just purchased a 2006 WRX TR last month, and still can't believe that it's parked in my driveway. My dream was to own an STI, but after test driving the TR.. it was exciting enough for me.. and just as awesome for what I could afford. I was driving a Scion XB, with just about everything done to it.. it was cool for awhile.. but I needed performance. My first two weeks of owning the car, I started to notice a loud *knock* noise, which turned out to be missing transmission brackets. The dealership said that it appeared they were never installed from the factory. They were cool about it, and fixed it without any question. After a proper break in of the TR, I didn't hesitate to dig into the performance parts.. starting out with an Omori Boost gauge, which I can't figure out why it "ticks" when at about 10-13 PSI. I have checked all connections for leaks, and made sure that it is mounted to the steering colum securely. Next, I went with a Kartboy short shifter & bushings. Knowing the potential of the WRX, I had to have the Access Port... so I ordered that.. and was very impressed with the ease of installation. The stage one showed some nice gains in power in 4th and 5th gear. I have been doing a lot of reading up on these very helpful forums, and also decided to do the silencer delete.. which is an awesome free modification. The sound of the turbo spooling, and a nice bypass valve sigh was quite noticable. Tonight, I installed an HKS hi power catback exhaust... very easy to install, and the sound is a nice low rumble. I am still debating which downpipe to install, so any recommendations would be great... I am looking for one with cats. I found an AWD dyno in my area last week, so I plan to possibly install the Street tuner AP... depending on if they mess with that or not. Either way, I plan to take a few runs.. just to see what the WRX is pushing out at the wheels. I will make sure to post some results just as soon as I get them. I had to express my excitement with somebody, who better than a group of people that all share the same passion. Thanks for taking the time to read, and I plan on gaining.. and sharing knowledge with you all.
