North America never officially received the first-generation Impreza WRX. Instead, we got the second generation model as our first chance to experience the performance of a souped-up Impreza.
Available as both a sedan and a wagon, here’s everything you need to know if you are in the market for a GD-chassis Impreza WRX.

Thicker front and rear anti-roll bars and new end links are another easy modification that will make a huge difference by reducing body roll and improving handling.
As for power, basic bolt-on modifications will yield some nice gains with a GD. A downpipe, cat-back exhaust and tune should produce right around 250 wheel horsepower and 280 ft.-lbs. of wheel torque. This is a nice bump over the factory output and can certainly improve the driving experience.

A tuning device is also a great base modification that pays dividends as your vehicle evolves. A simple tune will kick up the power a bit and unlock potential for when that downpipe and exhaust arrive at Christmas.
